I am thinking about up-grading to separates some day. Starting with amps first, using my h/k 320 as a pre/pro first, then changing to a real pre/pro later. Polk recommended amplifier power for my speakers is (all 8 ohm) as follows. RTi150; 50-500, CSi40; 10-150, FXi50; 10-150, RTi38; 20-150. The h/k receiver is rated at 55 w/channel and is never turned up past 0db (-80db to +10db manual warns not going above 0db) and that is plenty loud for me.
I have a few questions. Let’s say I’m looking at a 225 w/channel into 8ohm x 7 amp. Would I run the risk of blowing the lower rated speakers in my set-up, even if it is not turned up to very high volumes? Would I gain great benefits with separates, or should I get a flagship receiver instead (like the Sunfire Ultimate receiver [200 w/channel x 7] or is this still too much power)? What about bi-amping the 150s? Would they play twice as loud as the rest, or can you compensate using the channel volume settings? Please help with these crazy thoughts!
