If you look at the Yamaha website you can find some info on that. The htr line is sold at discount stores, while the RXV line is only sold at dedicated stereo stores. I think there are the same except the htr line doesn't have zone2, so you can't add an external amp to them. That's means nothing to me. I'm not going to buy a $500 receiver and then purchase a $3000 amp.

Charlie, out of curiosity, which model Yamaha did you choose?
