Hello all, new to the forums here. First let me say I am not a audiophile (ie I don't know much about hardware) just someone who enjoys music. I need to replace my system because it is to old. I started by picking out a speaker system - All Paradigm - studio 100s studio cc-590 center and a sub 12 and I would hopefully use my older Phase Techs for the back. I would like to buy a Denon avr to drive these speakers in surround for movies but 95% of my listening will still be music. What would be a "ample" supply of power for a 20 x 34 room without going overboard? I would like to get it right the first time. My music taste include just about everything rock, pop, jazz etc. Thanks in advance if you can help.
