I'm thinking of ordering a HTS 1000 MKII PowerCenter online for about $150 and was wondering if anyone has had any experience with it. I recently invest about $3100 in a system (Cdn $) and wanted to protect it. I notice my amp starts to hum a little if someone plugs in a hairdryer into the plug in I use for my system (Its all in my room). As well my amp recently went into protection mode and the warning light was because of DC detection. Would something like the Monster powercenter help for this? And is filtering really worth it or just more stereo hype?

Thanks
