Your mileage may vary when you get into the power conditioner shuffle. I 've seen almost every conditioner be recommended by audiophiles and then also criticized by other audiophiles for harming the sonics. Most conditioners get praised and then bashed. I have a Shunyata Hydra 4 which I like, but I'm looking for even more performance. One thing you want from a conditioner, like your physician, is to "first do no harm."
I just ordered a power regenerator, (APS Purepower), so I'll see how it is. Don't confuse power conditioners with power regenerators. A power conditioner filters the AC coming in, either passively or actively. The regenerators take the incoming AC, isolate it, convert it to DC and then back to AC (simplistic explanation). So you get isolation and a perfect 120 volt sine wave at 50/60 cycles. PS Audio has both conditioners and regenerators (power plants). The Audience is a power conditioner and the Isoclean is an isolation transformer. (not familiar with)
Whatever you buy, conditoner or regenerator, make a good attempt at being able to try before you buy. Or, if you buy used, make sure you get a good price so you can try it and resell it here if it does not measure up in your system. I've consistently been reading good comments about the Exactpower 15a and I almost pulled the trigger on one. Personally, on paper, I like the idea of power regeneration, since with it you isolate the AC line, convert it to DC and back to accurate, clean 120 AC. In theory, this is better than having a dedicated line if you don't have a power regenerator in the circuit.
