ReorX - You're going to be happy with a 650 or better, it's an excellent buy for the $. I just think hk is a bit too pricy.
I decided, to get the pioneer I'd have to return the yamaha, pick up the pioneer and I probably couldn't get the yamaha back for the same price, so I'm going to keep the yamaha (htr5760/rxv650) as a starter and upgrade down the road. To get the yamaha htr5790 I'd have to throw in approx 350 dollars and it's probably better to save that change and throw it in for a completely new model. I have to start from here, I wish I could go back. The yamaha 5760/650 is a nice package to start and I don't really mind the sound for music and there is some power there. More power usually does = better sound so I'd prefer a better model. I'm just going to use this one as a learner kit, it does have some cool features and is a good budget buy. I'd like to upgrade the speakers and rcv in the future. Right now I'm running 4 12" 3-way cerwins and a matching center (v-series), I also have two wharfedale *" 2-ways I can throw in for 7.1. I think the 650 is more than adequate for these speakers, I know their breaking points when the music seems like it will burst the speakers, I don't often have the levels high enough to do that but every now and then I know levels or volume must go down or speaker's gonna have a serious problem. I just turn it down real quick. What I'm saying is that this reciever is quite powerful enough, enough to dAMAGE my speakers by overpowering them. But that's not the issue, the issue is that the more power the better it sounds images and the like so yes I wish I had have gotten a better one, although this is quite a kick *** machine, but like the bigger amps are better. Anyways, I'm just going to have fun with this one until a couple years down the road then I''m going to get a better one, I'm actually looking for a 9.1 or more reciever so I could have a ****load of speakers like the movie theatre does. I love the big theatre sound and I don't like the little vip rooms it's more like a home theatre setup, it doesn't take enough control. The big theatres take full charge with authority. Anyways, I'm glad I'm kind of stuck with this one(5760/650) for the price it's pretty adquate, it'll help me learn more too so I'll know what I'm doing when I get a better one. Happy home theatre and listening.
