I use both an APC H15 and a Brickwall PWR2AUD. The APC is in my HT system and the Brickwall is in my analog system. Both work effectively in their applications. Tvad is correct regarding the Brickwall, although I notice a slightly clearer sound through it, it is minimal. The APC does improve video quality and allows connection of the amp and sub without current limiting and also has phone, coax etc. I live in the Midwest and this summer we've had horrendous thunderstorms and power outages. All four of my systems stayed protected.

Looking for surge protection and potential picture improvement (although my Panasonic plasma looks pretty good already) and need around 8 outlets. I'm considering the Monster HTS 950 or 1000 or the Furman PST 8D but I'm open to suggestions and thought I'd solicit thoughts/recommendations here before pulling the trigger. Thanks for the help.
