I just sold my Yami RX-V2500 for a Denon AVR-887. Cost me about $150 to do so. Was it worth it? Probably not. I lost some featuers of the Yami, and some power, and got up converting and HDMI Switching and outs. But I wanted it, the girlfriend is about to buy us a DLP 50 inch, which will be the total tits with my PS3 and the Oppo I get. That is why I got the Denon.
With all that said, the RX-v1600 has great reviews, and would prob be a great receiver for you, as would be the VX-v2500
