Hi, I'm new to the forum, and I am looking for a new A/V reciever. I mostly listen to music, but I also want to set up a surround sound system for watching DVD's. I like Harmon Kardon, after reading many reviews, and I don't know how many watts per channel I would need. I like to crank up the music, and mainly listen to rock. My reciever now, is an old JVC, 80 watts per channel. Can I get 65 watts per channel, and still be happy?
