I just picked up a Marantz MM-9000 to step up my HK 235 for HT. Is this amp going to make a noticable improvement on my system? I'm not too up on HK's low watt/hi current set ups? Even at 50w it's pretty stout. I just want to make sure I will be OK w/the speaks I'm powering. It's kinda late to ask since it's on the way. I think I need a pat on the head "or kick in the ***" Thanks!
