First of all, in my opinion -- based on all I could find to read on the subject of surge suppression -- there is nothing available that provides surge protection like a Brick Wall unit.
From Brick Wall's site:[size=xx-small] Quote:
A Brick Wall Surge Filter will never experience a surge related failure....
....Consider the following:
- IEEE (The Institute of Electrical and Electronic Engineers) states that 6000V is the largest transient that the interior of a building would experience.
- IEEE defines its harshest interior surge environment as one that could experience 100 surges of 6000V, 3000A in a years time (category B3).
- A new federal guideline recommends that a surge protector utilized in a harsh environment should be capable of withstanding 1000 surges of 6000V, 3000A or ten years worth of IEEE’s category B3.
- UL (Underwriters Laboratories) now provides a new adjunct testing service (in addition to the 1449 safety classification) that will test to the 1000 surge, 6000V, 3000A federal protocol.
Passing such a test is a virtual guarantee that a surge protection device will never experience a surge related failure.
Early in 1996 UL applied 1000 surges (at 60 second intervals) of 6000V, 3000A to an off-the-shelf Series Mode Surge Filter.
There was no failure. There was no performance degradation. Let through voltage did not exceed 290V. Certified by UL. |

I actually had a lengthy and cool conversation with Ryan at Brick Wall yesterday, and I'll post a little more of what he said if I get a chance to this weekend.
One of the things he did mention is that their rack mount units are generally not as quiet as the "brick" shaped units, for a couple of reasons:
- The "brick" shaped units have smaller outer surfaces than the rack-mount units, and so they're more rigid and less likely to vibrate.
- The rack mount Brick Wall units are only about 1 3/4" high, and so the inductor inside comes in closer contact with the top/bottom panels, making the panels more likely to vibrate or hum under heavy draw situations.
So, long story short, I'd recommend you go with a brick-shaped Brick Wall unit unless you really have a need for the rack-mount form factor. My brick-shaped Brick Wall is silent.
Read those specs quoted above again -- I know of no better rated surge protection devices (not to say they might not exist, but I've looked and found nothing rated higher for surge protection).
A bonus is that my Brick Wall did a fine job of quieting line noise my rig was picking up from other devices in my home (sump pump, air conditioning, etc.), and so improved my rig's performance.
If you can't tell, I'm a big fan of these devices, and may pick up a couple more down the road for my video system, as well as my office headphone rig.
