Check out Equitech products. They are the best company for balanced power sources. Balanced power is anything but "snake oil." Equitech's web site can explain it to you in detail. However, the first step (and I believe it the most important) is to make sure your audio system is on its own dedicated circuit(s). Adding a circuit or two is fairly cheap (and not very hard to do if your at all handy and have a basic understanding of electrical systems). You can go as far as you like with other things like UPS's (uninterruptable power supplies), surge protectors, voltage regulators, etc. but for most home systems (other than those for the obscenely rich audio perfectionists with a lot of time to listen on their hands) dedicated circuits are probably all you need. The second step would be balanced power (which usually also includes surge protection, and noise filters). The third step would be voltage regulation. THe fourth step... well after that who cares, at that point you've already gone extremely far. Why not spend whatever you have left on upgrading your system. You'll get more "bang for your buck." Good luck... hope it helps.
What should I plug my system into?
I just got my first high-end system, and without further ado plugged it all into a $5 power strip I got from the supermarket. As I read more, however, I see that one can spend thousands of dollars on line conditioners and other hi-tech gear designed to "clean" the power supply and otherwise work wonders when plugging in. I had no idea this stuff existed. At any rate, I suspect that, whether or not my ears can detect a difference in sound, it might be worthwhile using something a lttle better than a $5 power strip. Your suggestions would be much-appreciated.
