I use a brick wall, I took it out last night to see if I could tell the difference without it. If there was a difference it was small. I do not run my power amp through it because it draws a large amount of current, I have never heard that having a large transformer was a protection against dangerous current surges. It may smooth out small variations in current.
Surge Suppressor or Not?
I have an entry-level system (Cambridge 640 cd player, Parasound amp and pre-amp) which I can't really afford to replace if dead so am thinking about surge protection. Monster Power HTS2000 is about $200; Brick Wall PW8R15AUD is about $250. Are these good choices that wouldn't degrade sound unduly? Is there a better option?
I've been told that because amps have large transformers they don't need surge protection. Is that true?
