Hey guys, I've got a question. Let me tell you what I've got for context, then I'll ask the question. Got an Onkyo NR809 avr, Polk Audio RTi12 towers, and a CSi5 center. I've been working up to a nice Polk Audio HT and music system using the RTi stuff. Since I listen to music 80% of the time, I've been thinking about amplifying the towers. My thoughts were about getting a Parasound 2125 to give them a boost. If I get a second amp and run them mono to each tower, they are bridged and good for 400wpc and that sounds really good right? I'm thinking that'd be plenty of power but do people have good luck and sound with bridging amps?
