Yes. a surge protector is a good idea when lightning strikes. They do not affect the sound. They are easily made with a couple of varistors. Add an EMI filter and you have what most "power protectors" have for about 1/10 of the cost. There have been several articles in the electronics press about building one. A good isolation transformer with balance output is another good idea but not cheap. Plitron transformer site has an article on building one of these.
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?
