power conditioners


Idid not have much faith in this unit. I was baseing it mostly on lightening and stray voltages which where I live
wasn't a factor. At my bros house I saw and heard what happens when you overload your rig. He turned on an a.c. unit and you could hear some sort of interference and it was troubling to say the least. When the wallet says yes that's the next piece of my modest set. Hey, I'm learning and do take in opinions and read info so call me the sponge

With the high heat in some parts of the country now,the problem at your brothers may be low voltage.Another thing might be a bad relay,poor connection,or something else wrong with the a/c to cause a major change in the sound.
Often the ones built for surge protection as their main focus don't sound that good.

A good conditioner can make a big difference only after you have your system well tuned and properly matched.
A power conditioner, Furman being the best, is worth the investment, especially with you run tubes.
Furman is by far not the best but I like them. For the money they protect well and don't degrade the sound like others do but Shunyata, Running Springs, Audience, and Theorem are in an entirely different league.
