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.

Tiger Direct had (has?) a great deal on an APC H-10 power conditioner/surge protector. It seemed to make CD playback cleaner (like a slight veil was removed). Everything except the amp is plugged into that. I didn't like things (lost sound stage? depth?) as much with my amp plugged in so I just have that plugged into the wall. One of these days I'll spring for some PorterPorts for it.
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.
Brick Wall, SurgeX and Torus Power all license technology from ZeroSurge.
I use SurgeX SA1810 in both of my systems. I've powered Bryston 600/900 watt 7B SST monoblocks through them without any issue. I currently run active speakers through them with no problems.
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.
I was just repeating communications I have had with the founder of Zero Surge many years ago. And based on the About Us information on the Zero Surge web site, it looks like they were awarded a patent as recently as 2006 for their Total Surge Cancellation (zero let-through voltage).
Are you a representative of SurgeX? Can you provide a source for your information? And explain what 3-wire versus 2-wire technology is?
BTW, I own a pair of SurgeX SA-1810 products and recommend them highly.
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.
