Anyone have experience with "burn-in generators"?

Audiodharma Cable Cooker- Absolutely love mine! I investigated this and the Frybaby and picked this for its broader burn-in signal frequencies and higher signal amplitude for speaker and power cables. This device reduces the noise floor and opens up the soundstage. It lets you hear what'son the recordor CD. It does NOT affect the frequency response in any way! ICs are most improved I think because the typical signal strength is not strong to break them in adequately. You know that as if you take an old cable that's been used 1,000s of hours it still improves dramatically. You have to hear what these things do. You can play cable roulette all you want buying expensive cables but you're wasting your money without one of these.

Although I have no first hand experience with the Audiodharma I've heard many positive comments and have read several glowing reviews.

I have tried a bunch of different manufactured cables, and I have also made a bunch of cables from both bulk cable and also from basic wire and parts. Conditioning them with the Audiodharma Cable Cooker allows me to be more confident I am hearing what the cable can do and not the burn-in process.

i can second or third the 'audiodharma'. would not be without mine..great product.

It seems to me that the biggest problem with Cable Cookers is their manufacturers' claims that they can completely break in a brand new cable in 2-4 days. Imagine you have a new interconnect or speaker cable, which normally requires 250 hours of music signal to burn in. If it spends the first 4 days of its life on a cable cooker before installation in your system, my repeated experience (across a variety of cable types) is that it's still going to require 250 hours of music signal! All that cable cooking achieves is to make the cable sound less bad while you're getting the hours up.

Phono cables are a different issue, while several respondents also refer to using a Cooker to "refresh" well-used cables; I don't dispute any of those observations.
