"The differences in power conditions can vary greatly . Some improve the sound , some change the sound and some destroy the sound . "
Practically, I think that is the bottom line.
Personally, I'd lean towards vendors that specialize in this type of equipment as opposed to offering it as a complement to a more varied product line. Furman is the one that comes to mind that I would tend to have the most trust in and that I might test the waters with someday.
Meanwhile, my $100 Monster Power strip that I applied a few years back made a positive difference in the sound and I have tweaked the sound since via other means to essential perfection currently for my tastes, so I am hesitant to muck with anything, including the power at this point. However, I truly believe that power tweaks are perhaps one of the trickiest to get a handle on. The best approach I can see is to go with something that appears overbuilt for your application and consider it to be an insurance policy at a minimum, a clear sonic enhancement at its best.
