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?

Thank you, all, for your valuable suggestions. I found a post on another web site about lightning strikes and so searched web sites dealing with my area and found that we (foothills of Alberta, Canada) have the greatest number of lightning strikes a year in all of Canada so a surge protector will be a necessity.

In that price range, I would get the brickwall. Just remember that nothing stops a direct lightning strike, if that's what you're trying to guard against. Unplug during storms.
Thanks, all, for the excellent recommendations. I have ordered a Zero Surge unit with isolated receptacles (8R15WI) after checking out many possibilities (price/quality/performance). I would like to thank, publicly, Donna De Vico the Sales and Marketing Manager at Zero Surge for answering all my e-mail questions and then on Dec. 23rd when their company was on skeleton staff and enjoying a Christmas holiday luncheon she took my order and brought it to the Post Office. That is great service.
Bob_reynolds from 12-15-08 is incorrect in his statement. BrickWall, Torus Power, and ZeroSurge are licensees of SurgeX not the other way around. SurgeX is the only one with 21st century 3-wire zero let through technology while the other 3 licensees are only allowed to use mid-nineties 2-wire technology.
