I have the Sony STR-DA3000ES - I love it. I won't give it up until I get tubes (and I won't really give it up - just integrate it into the bedroom rig.)
That being said - I had never thought that much of Yamaha receivers until my friend auditioned his RX-V1500 - the unit really sounds nice. I prefer the Sony, but that Yamaha - not bad at all. Doug Oade has reported that the analog stage of the Sony x000es line is not so hot so the Yamaha may be a good solution if all of your connections are not digi-in...
