HK 630, OK NR900, Yamaha 2400, etc.. ???

Well, the sound is hard to compare becasue I have to listen to them at different shops and both sound great. I haven't taken either of them home. I really dislike Orange displays so the asthetics for me go HK , OK then Yammy.

Here is some specs on the 3 receivers for other comparisons (apologies for length) :

After doing months and months of research, I went with the AVR 630. I installed it this weekend and am in love with it so far.

I went to many an audio shop and I found that it sounded the best with the speakers I wanted to buy (Canton CD Series). So far it sounds awesome. I'm only waiting for the release of the HK DVD31 to complete my setup.

Good luck.

Thanks for all of your insight. I am going to take another listen to the Avr630. I have added another to my comparison -- the Onkyo NR801. Trying to weigh the power and inputs of the NR900 vs. newer model and styling of the NR801.
