This is my 5th unit from Dakiom so I am not surprised with the sound improvement it generates. I have made a habit of adding Dakiom to each new audio component I purchase. In doing so I feel I can get by with lower cost equipment and still get very satisfactory sound. The FM 203 is connected to the headphone output of a Apple Dual G5 2.5. The headphone is a brand new Sennheiser HD 555. The sound without Dakiom in the chain is acceptable. With it in it the sound becomes more relaxed and open. Most noticeable is the smooth and pure top end which made the listening so much enjoyable and non-fatiguing. After owning system that costed over 50K that became fatiguing after 1 hour of listening, this is what I care the most now about owning any piece of audio. Thank you Dakiom.

I first want to say that I am very skeptical about so-called “high-end” audio tweaks. I can’t think of a larger legal profit margin than that of audiophile tweaks.

Upon using the Dakiom F 203 over a week long evaluation, I must say that I am impressed. Don’t get me wrong, when I first plugged it in, the difference in sound quality is far less than a new amp or headphones. However, and this is a big however, the little Dakiom F 203 grows on you, and during my A/B/A comparison I wrote in my listening notes the following:

1. Less harsh highs
2. Greater and more focused decay
3. A veil is lifted - more detail
4. Less background noise

These are just cold analytical terms used when one really listens for specific improvements. The biggest and most obvious improvement is that music is simply more involving and enjoyable. I find myself longing to hear the next song on whatever album is spinning in my CD player at the time. I am sucked in. Yes, I have been asked to write this review as I receive a 40% discount on the F 203, but now that I’ve lived with the F203, I won’t go back.

Now that I've had a chance to 'bed in' your QR203 I'd like to tell you a fable. Once upon a time there was a young man who happened upon a love of Classical Music, and with his simple Pioneer Vinyl record deck...and...lived blissfully happy....One day strangers from the Digital kingdom came offering 'perfect sound forever', with their shrunken little discs....Of course we know such things can never come true in this fallen world. Naturally the man tried all the remedies: outboard DACs, expensive interconnects, stabilising platters, digital interface processors, digital antidotes; then turned to the dark arts of electronics itself, to occult components: Black Gate, Os-Con, Holco; their very names seeming to guarantee magical success. The poor man even tried to build his own monster...called the TDA1541 DAC chip with its two mystical Crowns. Then one day, defeated, in late middle age, he stumbled into a clearing in the World Wide Web; and found there a modest little sprite called Dakiom... with little hope...he...summoned this sprite home. And behold! a ghost came back to life of that musical love long since past. It was full and right shaped of body, delicate in touch, hesitant, sweet and clear - the love of old! Hermione lives! Perdita is found after all these years! (A Winter's Tale). Kim, stepping out of this rather stilted rambling, I'd just like to say thank you. Providence must have send you to answer my years of prayer. I cannot detail qualities of the music that your device accentuates or just boosts: it doesn't, it destroys something fundamental that had infected and cramped the sound. What is left is relaxed, weighty, easy, but full of emotion; like real things....

I am the owner of an old stereo system.... It consists of a Rega Planar 3 Turntable, Luxman R 3055 Receiver, Luxman K 8 Cassette deck, Revox B126 CD player, and B+W DM 14 Loudspeakers...Over the years I have tweaked my system with a filtered power bar, upgraded cables, and anti vibration sorbothane isolation feet. I thought my system sounded pretty good....And...In order to improve it I felt. I would have to buy new high-end equipment, which I was not willing to do. The prices are ridiculous! ...one day and I came across your website, "Dakiom". I read the reviews of past customers, and in all honesty it sounded to good to be true!...Being a skeptic I decided to purchase one stabilizer instead of two, the A203 for my receiver. I installed it and immediately noticed a subtle improvement in the sound... Each time it got better, reaching its peak after about six to seven hours of use. Being a piano player for a number of years, I trust my ears!...I invited my Dad over...we were sitting outside of the speakers in less than ideal listening conditions!...My Dad asked me if I had done anything to my Stereo. I did something I normally never do. I lied to him and told him I had done nothing to it! I asked him why he was asking, and he told me that my stereo sounded clearer than before....I did tell him two days later, and he was not upset. Any way I purchased a second stabilizer the QR203 for my CD player and cassette deck. Again like the first time, initially the difference was subtle, but after about six hours of use the difference was dramatic....The music sounds more real, like instruments not electronic sound....It's nice to come across a product that actually does what it claims....

We reckon the DakiOm R103 feedback stabilizer must be one of the great audiophile bargains. Installed in a wonderfully musical system we know well the DakiOm makes itself immediately effective. The volume level steps up and detail resolution is significantly better but without detriment to the familiar, relaxing musicality. Best of all there is no character change in reproduction and the R103 just lets the electronics do their job optimally. It may look incongruous to have little black boxes attached to your hi-fi but this one is highly recommended to listeners whatever their budget. Keith at Angelsound audio,
kind regards

I had originally planned to purchase the Model Fm203 and installed it on my computer's sound card outputs with cables running to my stereo. I feel this setup is where feedback stabilzers will sound their best. The effect of Fm203 is more pronounced when played through loudspeakers rather than headphones, in my opinion. I did, however, manage to sample some music through two pairs of Sennheiser headphones and found the upgrade to be equally impressive.... Rather than a standard review I would like to share some thoughts about how I think the feedback stabilizers might work for you, and possibly clear up some misconceptions about them. First of all, when you install these stabilizers into your system nothing is actually added to the music, and yet our perception is that…more bass, midrange, treble, energy, etc. … arrive at your speakers.…. it must be noted that the Dakiom feedback stabilizers are not signal processors, so to speak. One of the functions of the stabilizer is to restore what is lost by fine tuning certain elements of the signal, such as phase and amplitude, mainly by adding small amounts of feedback….extracting more signal where much detail would otherwise be lost, but also, more importantly, it will rejuvenate a degraded signal, which to our ears will sound harsh and glaring (due to a loss of information)….A common praise we hear about the Dakiom feedback stabilizer is that the system sounds more laidback or that the harshness has virtually been eliminated. This may be true, but not because the stabilizers have attenuated the higher frequencies. I believe it’s because these frequencies are no longer compressed (to radiate in a single direction) and have become appropriately dispersed across the soundstage…These are just a few of the many characteristics I have noticed from my system since installing Dakiom's feedback stabilizers. If you have a decent playback system and an excellent pair of speakers I'm sure you will notice them as well.

… I was… given permission to audition/review DakiOm’s experimental feedback stabilizer, the “Exp.F203,” for headphone/head amplifier applications. Given my very positive listening experience with just a single one of Dr. Dao’s 2-channel R203 stabilizers on my rather modest A/V system at home, I leapt at the opportunity to hear what DakiOm(s) could do for my headphone system at work ….In Brief:
The short version of this review is simply that the DakiOm feedback stabilizers work exceptionally well. Their performance is consistent, uniform, additive, affordable and preeminently musical. There was not a single application in which the DakiOm failed to satisfy—no, better yet, delight. They are versatile accessories that soon become staple necessities on the audio train.…Please understand that music has become essential to my sanity and survival at the office, combating the frequent tedium and frustration that goes with programming and debugging computer programs all day. Music provides a soothing, long-term backdrop to practically all my programming tasks, as well as the occasional short-term excursion into critical (and unabashedly escapist) listening. To begin, I tried the DakiOms one-at-a-time … Exp.F203…R203… HR203 … (January 27-February 10, 2005)
POSTSCRIPT April 05,2006
The new-to-market F203’s sound even more musical, liquidy, open and transparent than the test versions I auditioned last year. With DakiOms in place, be assured that you, the listener, leave few, if any, essential audiophile “stones” unturned.
DakiOm continues to deliver readily discernable, across-the-board improvement and musicality in the latest version of my dedicated headphone system, consisting of: …

Hi Kim, I received your 2 channel stabilizer today - thank you. My review follows (make edits if necessary): I received your 2-channel headphone stabilizer today. I must say that I was a bit skeptical prior to using it with my Sony portable CD player and Grado Headphones. I am used to listening to my main system of stacked Quads with Decca tweeters and Futterman amps. Without going into all that Golden Ear details hooplah, I must say that listening to my reference cd recordings became more cohesive, and immediately more rounded, as compared to the cardboard flatness I usually hear with this headphone cd combo. The stage opened up and the music just sounded more like music:) I did not hear a deeper bass improvement, nor a louder presentation. Just a great more involved musicality. Thank you, B. R.

I am stunned with the change in Sound after installing the Feedback Stabilizers in all points in my Audio Chain. Although, I have a fairly hi-end system, I did not realize that this meager investment will make such an improvement. The midrange has bloomed, the high frequency is smooth as a velvet, the bass is controlled and tight (I was earlier wondering how to control due to poor acoustic of my room)a and top of it the imaging is superb both vertical and lateral. The transients have also improved dramatically. …To sum up, I am extremely happy and satisfied with your product. Thanx for the deadly creation at such a reasonable price!!

…Dakiom has a 30 day money back guarantee that seemed pretty iron clad, so I decided to give them a try, … with my Marantz CC4300 CD changer. 

R203 on Marantz CDP

…As a general rule of thumb I do not like having to strain to hear differences …I have to be absolutely convinced that the new device makes a noticeable difference ... That said, I remember that it took me about half an hour to figure out what the Dakiom R203 was doing to the sound from my Marantz … instruments and voices became more real, almost visceral and exciting … piano, in particular, became more natural and true to timbre. …The shimmer from cymbals became more apparent. There was absolutely no drop in dynamics, … making the bass sound more natural and less boomy. ...Busy music with a lots of percussion, cymbals, brushes and maraccas that used to sound blurry sounded more focused and separate. … I was hearing details I never heard before. …All the same, my system sounds closer to the truth with the Dakiom. Not to be left out is the Dakiom's ability to removes listener fatigue. I could relax and listen to mustic for long periods of time without being fatigued. 
…With the R203 removed, the realism and excitement diminished and white background noise became more noticeable. Just a few minutes of playing my system without the Dakiom was enough to convince me about the effectiveness of the product. …With the Dakiom reinstalled the notes began to just flow…. 

R203 on Tube Audio Design TAD-150 Preamp 

When I tried the R203 on my TAD-150 preamp outputs, … it did require me to put some effort a to hear differences - contravening my general principle not to have to do so. So in the end I removed the R203 from the preamp and reinstalled it on my Marantz CDP, where it had the biggest positive impact. 

A203 on Cayin TA-30 amp 

…After installing the A203 on the outputs of my Cayin amp …, I pretty much heard all the improvements noted above with the R203, but the improvements were further magnified. …In terms of incremental improvement, the A203 made a much more dramatic improvement than the R203, and it required no special effort to feel the change. ..There was a break in time 10 - 15 hours after which the soundstage opened up further and top end become even more clear and "bell shaped" smooth. Then for the acid test, I took out device from my amp and listened. There was an immediate constriction of the soundstage and drop in realism! It took me no more than three minutes to decide that the A203 needed to be back on my amp!! 

Conclusions 

I am absolutely convinced of the value of the Dakiom on my setup. …took my system to new level in enjoyment and emotional connection to the music. The impact is exciting and visceral and got me closer to the truth. They allow you to hear the essence of the music …I definitely cannot remove the Dakioms. They are like missing pieces of a puzzle in my system.

I bought this more out of curiosity than anything else and as the price was very low. I thought: "what the heck! I'll give it a try!". I must say that more or less it does what it claims: slightly tighter bass, slightly clearer imaging, slightly more natural vocals, slightly smoother highs... in two words: slightly better. So really it is up to you to decide whether it is worth it. I think there are better things to buy first with 99 bugs: better headphones being the first, or a better player. But if you already have a top of the range portable set up, then this won't break the bank and it might add a bit to your sound.

… I decided to try one device (A203) …I had a Pioneer(cheap) …this amp sounded so bad I was barely able to listen to it for more than 15mins at a time. However when I put the amp stabilizers (A203) on, the sound quality dramatically increased and was actually musical. Then I tried the amp stabilizers on my Carver amp. The effect was noticeable but it did not make a dramatic change … However I was looking at the web site again…and noticed that some people said the biggest change happened when all the interconnects(R203) were done …I wasn't disappointed in fact I am absolutely amazed at how good the sound is when all the interconnects (CD and preamp) have been stabilized. The clarity of the sound increased …But the biggest difference I noticed was in the soundstage. The Carver pre-amp already provides excellent soundstage with it's holographic sound but with the stabilizers on this was increased another notch. To me the only way to describe it is like putting on "audio glasses" for the first time. …Now it seems like the individual sounds come from distinct locations with total silence in the areas between. Amazing!

…I decided to add the final stabilizer to my system the Fm203…I think the greatest improvement comes from the soundstage size; but with headphones, the soundstage size is limited to the distance between the ears. So although I didn't notice much difference in sound with the Fm203 when used with headphones … I did notice a big difference when used to hook up the iPod for external playback (through my stereo).

Honestly these devices to me represent one of the biggest advancements in musical enjoyment for the money that I have made …I personally love listening to music and these devices have made listening all the more enjoyable. Thanks.

THIS IS MY SECOND REVIEW: After being very impressed with the home theater package HR/HA-103, making a detailed review, I quickly re-ordered a two way stereo package R-103 and A-103… Tweaking a system is my FORTE' I did a variety of tests…. WITHOUT THE DAKIOM'S and all processors BYPASSED, the system SOUNDED plain and clear due to the MAGNEPAN .5 and CARVER system. With the DAKIOM'S installed, like my previous review, the SPEAKERS CAME TO LIFE, and THE CARVER AMPS/PREAMPS really comes to life, as great the circuitry in ALL CARVER EQUIPMENT, the DAKIOM'S enhances them to THEIR FULL POTENTIAL. Now I ENGAGED all the processors, one by one...the DAKIOM'S in each processor IMPROVES and WIDEN'S the AUDIO SPECTRUM on each processor. ... Like I mentioned before, whatever the DAKIOM stabilizer TOUCHES, it adds FLAVOR and IMPROVEMENT beyond what your EARS CAN "LIVE WITHOUT!" The better your system, the more MUSIC and LIVELINESS it brings out… FOLKS! This is an AMAZING PRODUCT and HIGHLY RECOMMENDED. You are wasting money, by not INVESTING on a SIMPLE yet very EFFECTIVE device that is MULTI-PURPOSE for HOME, CAR, RV, BOAT whatever!

"AT THE BEGINNING WAS CHAOS AND THEN GUYS AT DAKIOM CREATED FEEDBACK STABILIZERS"
... I decide to attach HA-103 AUDIO STABILIZER first. My first movie X-MAN 2, i must have seen that movie dozen times but what i heard was totally new soundtrack. The opening scene in the white house blew me away. The effect of that scene were reproduced with such detail and dynamic that got me off guard. There was so much more to bum and bang , specially bass area become clear and define Finlay bass get rid of the mud. Next movie was Lord of the Ring fellowship... Amount of detail in quiet passages of the movie was incredible for the first time i was hearing wind, leafs rustle , and even rain got a new life. On the next day i was so excited to attach HR-103 but i could not imagine how it could make things even better.... First movie on the menu MATRIX RELOADED. Oh boy i was not prepared it seams that more STABILIZERS MORE IMPROVEMENT. HR-103 bring new meaning to a word SURROUND for the very first time i was sitting totally immerse in 360 degree sound field, suddenly sound was coming from all speakers ( 7.1) with equal power and clarity. Something else happened also sound become transparent as well as very well balanced.... To decide if that changes ware true i disconnect STABILIZERS for two days and watch the same movies for point of reference. Well doing so i would recommend clear the path in front of equipment because you will run, yes run to put them back.... STABILIZERS ARE STAYING IN MY SYSTEM FOR GOOD, CHANGES ARE TOO BIG TO LIVE WITHOUT THEM. OF COURSE CHANGES MIGHT BE DEPENDABLE ON MANY THINGS BUT THERE IS ALWAYS GREAT SUPPORT LINE THAT DAKIOM PROVIDE. I WOULD LIKE TO THANK GUYS AT TECH SUPPORT FOR ALL HELP AND ADVICES CONCERNING ATTACHMENT OF STABILIZERS. THANK YOU VERY MUCH FOR INVENTING SUCH AN INCREDIBLE PRODUCT.

...Noticed a wonderful difference in my audio system right away after installing the Dakiom Audio Stabilizers, there is no doubt this product can and will improve you're system. The stabilizers seem to smooth out the rough edges of the music, i now listen to c.d.'s that were barely audible before because of high pitch noise and other unwanted sounds.... the Dakiom Audio Feedback system is the best deal, no doubt about it. The mid-range improvement was significant and the high frequency range was smooth with a nice pop sound to the bass with a more suitable and distinct sound. I would also like to say that my headphones (Sony RF915 series) sound much better, they came to life, the music was more suttle with a nice punch to them. I highly recommend the Dakiom audio system to anyone out there who enjoys music like i do.

I have been using ... A103+ and ... R103 for a full month now, so I am to be sure and write an accurate review of the products. One note, first off, is that they do sound better after a short break-in period. My first impression ... was very good, but I had an impression of a little lost clarity in the treble- less "attack." After listening to these more and more, and especially after taking them out for awhile, I realized that the only thing that was gone was the feedback distortion. I was mistaking the harshness for loudness perhaps, my system definitely sounds more musical now. It is amazing to find out how bad your amps actually sound when you find out what these little things can do- taking them out after listening with them in for awhile makes music- especially "busier" music like rock- sound like it is coming out of a cave.... I always felt like there was something wrong, something confused between the "music" and the "audio" that was interpreted.... but the stabilizers remedy nearly ALL "LISTENER FATIGUE".... this seriously and truly is a breakthrough for the audio world, and I would recommend for anyone that loves music to give these a try. Even the "eliteist" audiophiles with megabuck systems- your amps have some of the basic circuit designs in common also. I would classify the stabilizers not as an add on, tweak, or refinement, but as the missing stage of an amplifier. Someone has finally found out how to solve the problems that arrise from the use of negative feeback, without taking away the benefits. And to do so passively. That is awesome.

... I have never come across so many reviews on one product-Dakiom feedback stabilizer, especially all are favorable reviews. As I read through them one by one, I wondered whether they are true stories and I hoped that I would get the same feeling and the kind of described effect on my system.... To my surprise, I am happy that the reviews are so true, with the stabilizers on, the sound is very pleasant to the ears, which is smooth, airy, musical and detail, even the volume is turned down a bit lower than usual, the music is still clear and outstanding. I can now settle down and be relax to enjoy listening to music instead of thinking about other tweaks to improve my system. I will tell my friends about this valuable product. Best Wishes!

... Like many reviewers, I was astonished by the improvement these products made in my system.... The Jazz albums that I have grown to love immediately took on a new, more lifelike, quality. Simply put, they sounded more "musical." ...In each case I found myself more deeply involved with the music than I could ever remember being. I suffered the dilemma of every audiophile who discovers a hot new product. The music sounded so good I wanted to keep listening; at the same time, I wanted to hear what the product could do for so much other music I have in my collection. I don't pretend to know how these stabilizers work, but I am convinced they do. The most notable immediate improvement was in the bass, which was tighter and more focused. After listening to some of my favorite (and familiar) classical cds, I noticed a similar improvement throughout the critical midrange. Individual instruments were better defined and the sound stage was deep and well layered... But to my mind the main improvement was not in the details but in the overall presentation. Rhythms seemed to flow more naturally and the music seemed more like a live performance. Isn't that what audio reproduction is all about? ...The effects of adding stabilizers along the chain are cumulative... In terms of price vs. performance I can't think of a better product, and I now consider the Dakiom stabilizers an integral part of my system. With the money-back guarantee you really can't go wrong. If you love music, you owe it to yourself to try this product.

I was very pleased with the sound quality I was getting from my sound system, so while I had high hopes for the Dakiom products, my expectations were fairly low. Consequently, when I installed the feedback stabilizers and couldn't really tell much difference, it came as no big surprise. I noticed that the bass seemed slightly more pronounced and articulate, not big and boomy, but a bit tighter and more defined. However, I chalked this up to the placebo effect. Wanting to give the stabilizers a fair trial, I left them in for a few weeks. At the end of this time, I decided I should make a decision, so I did a 45-minute listening session with all types of music. Then I removed the stabilizers and begin to listen to the exact same music again. I only listened for about five minutes before I decided that I wanted to put the stabilizers back in. Without them, the music seemed harsh, especially high frequencies and vocals (sibilance, etc.). Also, I decided that the change in bass I had noticed before was very real. This is an excellent product, especially at the introductory prices. Had it not been for the low price and the money-back guarantee, I would never have tried them, which would have meant doing myself a great disservice.

...I am Augusto Sampaio, a pediatrician and music lover living in Brazil...  started around 1970. At that time, I already had a dedicated room for listening recorded classical music. Fifteen years later, I built another music room, so important for me as my new house and bought my first CD player... I was secure that my happiness would be forever. Not yet. Soon, I discovered some new bad companions such as jittering, not very wide soundstages or worse, flat ones, and a much easier hearing fatigue... It was time to move again. In my third and smallest listening place, already in the 24/96 new era... I could feel I was closer to my missed LPs sound, but still it was not enough... The chain for creating an analogical curve was almost complete when I read in one of the last issues of Bound For Sound some commentaries by Mr. DeWulf about the Dakiom feedback stabilizers A 103 and R 103. I ordered both. It is amazing how there is always a space for more improvements in the audio art... Don't ask me how technically those little passive boxes work. I am only a veteran sufferer audiophile with a pair of reasonably trained ears, not an electronic specialist. What I know is: the results have been the closest to everything I as looking for... Now, more than ever, I spend my free time listening to music analogically relaxant... I think that any serious audiophile deserves a trial with these little, but essential, Dakiom stabilizers.

I was skeptical of this product based upon the wild claims made in the advertisements. But, after reading some of the reviews, in a moment of weakness I decided to give them a try. I figured that I would try them for a week and then send these things back and easily dismiss these little black boxes as snalke oil and move on. My first impression was that they made the system sound different. I didn't necessarily think it was better - just different. I could only listen for a song or two - then I had an errand to run, but I pretty well decided in the car that the things were going back. Later that evening my wife and I sat down to listen to some music after dinner, and halfway through the first song she commented on how clear the vocals were - she had no idea I had done any tweaking. By the end of the listening session I had turned from skeptical to absolutely delighted. The soundstage deepened, instruments were more distinct and clear - even pitch and rhythm were improved. I have had them for a couple weeks now, and I notice myself digging deep into my old CD and LP collection and enjoying music that I have not listened to in years - it all sounds so fresh and new. These have given me great enjoyment, and I highly recommend them.

I purchased the Home Theater Base Package & extra HR 103 feedback stabilizers for my home theater system consisting of an Harmon Kardon AVR-85 reciever, Paradigm Monitor 7 front, CC-350 center and Mini Monitor rear speakers. I first installed the HR103 stabilizers to the pre-amp out of my Harmon Kardon AVR85 Receiver and tested that alone. There was an immediate improvement as I could hear cleaner sound and more openness. My Wife thought she could hear a difference (She's been my ultimate resource for years of trying new tweaks) (If she can hear it there is a major improvement). I next installed the HA103 Amplifier stabilizer to my speaker outputs to my speaker system. On listening to a wide array of music, I was amazed at the way instruments just seemed to pop out of the air with a transparency and openness I had never experienced with this setup before. My wife was also impressed in a way I had never seen before with all my years of modifying amplifiers, building speakers, experimenting with sound deadener products, etc. This 'STUFF' works!!!

... As a former musician, I was dubious as to how much of a difference the stabilizers would make, especially on my novice audiophile system... Well, the answer is a big difference. After doing blinded tests, I always come to the same conclusion. The music just sounds better. After putting the stabilizers on, the music is more lifelike, and more beautiful than before. Now I find myself more involved in the music, and just plain grinning more. Thanks for a great product at a more than fair price.

... I was already very pleased with the sound quality I was getting from my sound system, but I am in a constant "state of tweaking".... Going back from the stabilized state to the non-stabilized state really made a big difference and I could not bear the harshness of the sound without the stabilizers. This is really an addition to my system, and as stated on the web site , try the dakiom stabilizers first and you will feel no need anymore to spend hundreds of dollars on expensive cables.

... As I have listened in the days following, I find that I would have to wholeheartedly agree with the claims made for these products. Bass is indeed deep, tight, and tuneful, but without any sense of bloating. The soundstage is open and airy, and is both wider and deeper than it was previously. Imaging is excellent, with instruments precisely placed in the presentation. What stands out for me, however, is the more realistic sizing of the instruments. Acoustic bass sounds like it's coming from something the physical size of the real thing! Everything has excellent tonality. Complex music is more easily resolved...... clearer. The music is alive and in my room! Since my Unico has the built-in phono stage, I also get the benefit of the A103 when playing vinyl. The more I listen....the more I hear the benefits! I'd recommend these products to anyone looking to improve the sound of their system for a very modest investment.

Wow I bought a set of Dakiom Ma103 for my Parasound Hca 3500 and what a differnce it has made in the overall sound quality .I have tried with them and without them countless times. Ive had my wife listen to the stereo with and without and she is not a music buff and she could not believe the difference it made. I have been tweaking my system for two years and without a doubt this is the most bang for the buck out there bar none.In conclusion all I can say is don't think about it any more BUY THEM you will be happy with what you hear.

... The improvement are that you hear a deeper tighter bass...not boomy and less distortion..........a much more three-dimensional sound..........less harshness........I also heard more inner detail in well-known recordings.........a broader and deeper soundstage, with very precise placement of voices and Instruments, both laterally and in depth..........The improvements are Dramatic!.........My stereo system is now more transparent.....the inner detail, transient clarity, depth of image, texture, dynamics and life-size stage has to be experience to be believed!!!.... There no need to see what the difference is with the stabilizers out of my system, the difference is Night and Day with the stabilizers in my stereo system! Update....... I order another stabilizer (R103) for my Satellite receiver and now my receiver does not sound Harsh or Dull now....

... wow how much more music there was with even just an entry level TT and vintage separates. But I wondered if I could get more. Seemed something was missing, i.e.; soundstage and being able to hear separately the different voices or instruments. I thought monitors, better components etc, etc. I decided instead to try a tweak. After much surfing I decided on the Dakiom Stabilizers. What a total improvement! Now I have a soundstage, I can hear everything, that seems to be in the grooves. Tight defined bass, clear as a bell highs... In any event I have settled on this final descriptive analogy with the Dakiom Stabilizers I feel as if I am in the recording studio listening to the final master cut as the engineer and artist intended for it to sound!

The very first thing I noticed was the tightness of the sound by system made after installing the R103 and A103's, especially in the bass region. Excellent sound. The next impression was in the imaging improvement in my system. The spacial sound of the instruments was impressive. I could not only hear each instrument, but I could also sense the space around each instrument. It is a joy to listen to the music using the R103 and A103's. I have no idea how they work, and I do not even care. All I care about is enjoying the music, which I do to great extent.

First of all I was not looking to tweak or upgrade my current audio system. I was just looking at Audiogon to check on what the going market was for Def Tech loudspeakers.... until your ad for stabilizers that is,... and decided to take a gamble and see if there could be a slight improvement to my audio system.... Now my Monitor Audio's come alive, better bass slam, improved midrange and nuances that were not there before, highs are even clearer than previously noted. The cymbals sound like they are in my listening room and I am drumming with the band. The biggest test was when my wife called to me from upstairs and said she thought the vocals by Patricia Barber, Diana Krall, and Joni Mitchell were more realistic and she had to run downstairs to see if I had purchased a piano for our listening room! ... I am definitely going to let my friends know about this product. Give this product a try you will not be sorry. As for the return label in the box, it is now somewhere in the bottom of the trash. These are keepers. Happy listening!!

Hi DakiOm, Upon plugging-in, I did not notice that much of an improvement, with the exception of more accurate bass and increased bass quantity. However, after about a week's worth of continuous use, the DakiOm blossomed into something that deserves to be at the top of the value list. Music was much more involving and emotional, and you don't even have to try hard to notice the difference. I also noticed a significant improvement in dynamics. I've used the HR103 on my receiver, and the difference is phenomenal in favor of the DakiOm." "The DakiOm made me re-tweak my Yamaha mixer, and re-adjust my speaker placement, and everything sounds great...so good in fact, I now understand terms like "open, airy, focused bass, harsh highs, sound stage, transparency..." Thanks.

I wanted, on AudioGon, to change my speaker cables and D\A. I've seen many times the DAKIOM STABILIZERS, but was not interested, even in last week. I first ordered X-103 and put it in the DAC. DAKIOM transformed the already good sound into better sound. The voice is clearer, details for all instruments are enhanced. I listen to all my CD’s and feel like listening to new CD’s.I ordered one R-103 and put it in the cable converter and two MA103, thus upgrading the analog sound from cable. The improvement is amazing, more sound stage. The channel separation is incredible. More transparent high-frequency, smooth and natural mid-range, and much more solid bass. In all aspects it is extraordinary performance. I change my mind about changing my D|A and speaker cables. THANKS DAKIOM
