Not for amps, quash dynamics, at least for demanding high current tube amps. This is one of those you have to try for yourself deals. I prefer conditioners on everything but amps. Battery powered components or powering with batteries another scheme I've used.
Power Conditioners
I am curious about people's experiences w/ the effectiveness of power conditioners. Do they have more of an effect on power amps vs. digital components? How about turntables, CD players & TV's? Are the less expensive ones worth anything other than maybe surge protectors? Should you run everything through them even if you have other outlets available that are on separate circuits? Thanks for any help.
