I have a small spare bedroom that I am converting to a small man cave. Measures about 15X18. I would like recommendations on a 2 channel receiver. I'm thinking about 75-100 watts per channel. I already have a pair of Klipsch Heresys. 75-100 watts could probably over power the room, but I want to make sure I have enough power to eventually move to a larger room. I have been out of the audiophile game for a long time and am now ready to ease back in. I'm most concerned with sound quality. Thanks for your help!
