What about Power Conditioners?

But, I've not tried the really expensive regenerators. All the "conditioners" that I tried sounded worse, having the greatest negative impact on amplifiers. However, I'm fortunate enough to have very clean power running to my house and a short run from the power pole transformer that serves only my home...country living and all that.

If someone has noisy power for whatever reason, they may find them more useful than I did.

Like almost everything in audio, it's not universal in application and often ends up as a trade-off of some sort.

Btw, one of the ones that I tried came in around 35 pounds and was huge, while the others were far more light and modest in size. The resulting sound was either indistinguishable from using the wall directly or noticeably inferior to using the wall directly. Interesting and very surprising, the one that had no effect of any kind that I could distinguish was a Radio Shack model about the size of a hockey puck and cost all of ten bucks.

Happy New Year- Rich.

Much like cables/power cords, line or power conditioners are filters, as well. Some are excellent and some are poor. Some will "steal" current from your power, while others will not. My best advice, based upon where you live, it to listen at your local dealer/retailer.
If you own your home consider a dedicated 20A line first. This can be installed by a certified electrician.

indeed. if you can't do that, a good power conditioner makes sense. but i would keep it basic, you don't want something that chokes out power supply (and some of them do). in my experience, the power conditioners that work most universally are heavy units. i have a API Powerwedge 112 i shall always keep around, i don't think it's made anymore and the owners seem to keep them, since i have tried to score another one and can't (and they should not cost more than $300 these days). also, some amplifiers do better than others with power conditioners. some new premium class D designs specifically warn a power conditioner may impact performance negatively. i recently got a NAD M22, and it works well with the Ultra 112.

do never expect to hear big differences with these tuning things - it is to a large degree for piece of mind, and basically protects your equipment from surges primarily, and just barely may provide an extra ounce of clarity. i have it in there, for the life of me i am not sure i can hear a difference. the system sounds pretty darn good without it too. :-)
