There's a company called DAKIOM that claims in so many words to have found the "holy grail" to audio nirvana! They are making some pretty incredible claims. This is taken from their website...
=====================================================================
A $200 amplifier wearing DakiOm Feedback Stabilizers can sound noticeably better than a naked $2000 amplifier, even to the ears of ordinary people! (...Put a Feedback Stabilizer on the $2000 amplifier and the sound will be even better.)This may sound like an extraordinary claim, but hearing is believing. For example, take the HomeTheaterDirect.com Stereo Amplifier A2100 (100 Watts per Channel, $219) which one can buy online (we have no affiliation with them). Connect our A203 stabilizer to the speaker terminals and R203 to the line-out. (Even if unused, stabilizing the line-out reduces noise in the amplifier). The A2100 + DakiOm sounds better than any un-stabilized amplifier under $2000. If fact, let us know if you can find a stock amplifier under $3000 that is better sounding because we haven't been able to. If you add all our DIY tweaks to the $219 A2100 amplifier, especially project #3 with another A203, this combination will compete with any un-stabilized amplifier regardless of price.
=====================================================================
I haven't made a final decision on DAKIOM and their claims, so for now this is just a post to expose others to what they say and believe. I'm curious what the technically adept members such as tomservo and/or jneutron, as well as others here have to say about DAKIOM's claims. So please persue their site and tell us what you think about their claims after you've looked through their website.Thetubeguy1954

Hi.Whatever is added to the speaker terminals, PSU, interconnects, etc etc, discerned ears can detect the difference, be it DekiOm or XXX.
Better or not sounding is another issue. Sonics is so subjective.
If 30-day money guarantee is appliable, there is no harm to try them out given no distructive modification to the existing geas after removal.
Commercial claims should not affect our music instinct, right?
"The A2100 + DakiOm sounds better than any un-stabilized amplifier under $2000."Statements like this are red flags.
This is a statement of opinion as though it is fact.
I doubt there would be universal agreement. In fact, I'm sure there would not be. This kind of puffery makes me doubt the rest of their claims.
These remarks were taken from their Audiogon Ad...Dakiom MA253, best match for your expensive speakers
As time goes by, Dakiom theory on ways to achieve sound quality of amplifiers becomes more relevant and snake-oil propaganda becomes more irrational.
You don’t have to worry about electronics any more. Dakiom already offers you the best in sound quality as audio electronics is concerned. By the way Dakiom confirm that DVD-A/SACD are superior to all and you must support them because CD can be boring.
Just concentrate your resources (time and money) on finding speakers. Sorry we can’t help you here and nobody can. Not to sound pessimistic but history has shown that it is hopeless to count on advertisers, reviewers, forum buddies to lead you to what you want. They are all pushers. They will cover-up accurate information and give you mumbo jumbos promoting their snake oil. It is the nature of the beast. It’s food fight between “hired guns” cheerleading for brands. Forums are for advertisers, not serving consumers. Allusion, human frailties are their field of exploitation.
They can even make you defenders of their snake oil. They lure you in, but don’t get stuck in there, prepare yourself to switch side in a flash any day. It’s all mumbo jumbo anyway, why suffer an ego bruise every time you are tricked. Everybody is deceived at least once.
Don’t be associated with the “delusional subjectivists” nor with the “tin-eared objectivists”. They are all set up by the pushers of snake oil. The delusional subjectivists take you to the land of placebo to sell snake oil and the tin-eared objectivists take you to the land of emptiness in order to make the delusional subjectivists appeared reasonable, again both camps in concert sell snake oil. Try Dakiom products, you will hear the delusional and the emptiness aspects of miracle wires and megabuck stuff.
According to them, subjectivists are wrong & objectivists are wrong but Dakiom has the answer and their products are the only non-snake oil products out there. The complete Dakiom AD and what they say can be read by clicking on the link below.

Hi TubeguyWell a couple of the others hit the nail.
Amplifiers (open loop) are normally limited in bw by a first order slope (-90 degrees), this insures that at no frequency is there more than 90 degrees phase when gain is greater than one. This is usually an RC filter which has a lower corner than all the other corners which the various other R’s L’s and C’s in the amplifier parts cause.
What the ad copy writer may not be aware this is called “Bode criteria” which defines unconditional stability. Having positive gain AND 180 degrees phase shift is an oscillator.This device is not “in” the feedback loop, it is tied to the output between the amp and load.
The only thing that could “improve” feedback stability (from the outside) would be to lessen the load at high frequencies (via a series L).
This (if large enough) would be audible as it rolls the hf off.
To the listener, a speaker which is flat sounds very bright even brittle. People like a rolled off high end and an inductor is about the only part small enough to have an effect and fit in the package.Tell you what, I am curious now about your RCA’s and what you would think of them if they were dialed in.
If I remember, you didn’t have any drivers for them.
It’s spring here, my measurement tower is up and running in the back, if you send me one of the boxes empty in a re-usable box, I’ll figure out some drivers and crossover and ship you an empty box back and a list of stuff.
I re-did an A-7 driver / crossover a few years ago that turned out very nice but it required some internal bracing (which even shows up on the TEF haha) so it would make sense to do this before the boxes are nicely finished etc.
If interested, write me off list.
Best,Tom
Tom,I really appreciate your offer. Believe I understand how generous an offer it is! Unfortunately I cannot afford to send one of the RCA LC9A cabinets for a few reasons one of which is insured it's almost $400 to ship. I just obtained 1 original working crossover, the specs of an original 16 ohm woofer as taken from from an LC9A cabinet and the knowledge that the original tweeter an RCA MI-11419 is actually just a relabled 16 ohm JBL-175.
So if you have access to an working JBL-175, I could send you the crossover (as a guideline?) and the specs of the woofer. Would that help? Sorry I missed you when you were in Orlando, I really was hoping you could see the LC9A's as well as hear my audio system. I would have enjoyed hearing your opinion on how my system sounded to you, no matter what it was.

Well the claims about the positive feedback was not written my any engineer who knew what he was talking about.
Any competently designed amplifier would not allow the NFB loop to ever go positive within its design specs.
Any device outside of the amplifers NFB loop like their R203 cannot effect the NFB, let alone be capable of "sensing" the state of the NFB loop inside of the amp.
Given the price of the A203 i would think it is just some sort of snubbing network device. I would hazard a guess at a 0.1mdf cap and an 8 ohm resistor or similar. Such a device would be able to affect the NFB loop assuming the NFB point is connected from the output transistor pair, back to a previous stage within the amp itself. But its effects would be to reduce the possibility of RF instability caused by the phase changes at high frequencies although these usually only ocure with high capacitance speaker wires.
In any case, a few bucks more spent on these magic components would make a $200 amp compete with, if not sell for $2000 ! why isn't every manufacture doing it ?
Interesting... Thanks for the link.Since their DIY stuff seems sensible, I'm less inclined to reject out of hand the notion of inserting their non-linear gadgets in the signal paths even though that is typically an anathema. Likely the devil's in the details. Sounds like they are along the line of Al's RC dampers.
