I think I'm going to go with the Yamaha RX-V659. I can get this shipped for around $350 with no warranty or $400 with a 3 yr warranty.
For my setup, I cannot find another receiver that offers auto-setup features (YPAO for the 659) and 2 zone capabilities (with pre-outs) so I can send zone 2 to another amplifier (for whole house audio - probably via the Russound CAS44). I also like the idea of the "compressed music enhancer" as I will ultimately be streaming MP3 files from my computer to the receiver.
If anyone has other suggestions for receivers in this price range (around $400 shipped), I would be interested in your opinions. Again, I'm going with the Ascend speakers (CMT-340 x 3 and HTM-200 x 2).
Thanks,
Chad
