Summary: Wanted a 7.1 Channel Receiver with the new HD lossless sound to replace my Yamaha HTR-5750 and to go with a new Panasonic Blu-ray player. Read too many reviews of the Onkyo 606 heating up, so didn't even bother. Tried the Yamaha RX-V663. Although it had a decent sound, which is why I gave it the three stars, it would not pass the Cox Cable HD DVR signal thru to the TV. The TV just flickered like crazy.
