Got this reciever to hook up a wii (component), time warner DVR cable box (component), ps3 (hdmi), and an xbox 360 (hdmi). Works great with passing analog information through the hdmi. I have a few issues with it. For whatever reason, after a few months it stopped recognixing dolby digital signals through HDMI from either my ps3 or my cable box. Had to hard resest to get it working again. Other than that this thing is built like a tank and I am very happy with the purchase

The main selling point of this receiver is its HD Audio capabilities (Dolby TrueHD and DTS Master-Audio)and this was my main motivating factor for purchasing the RX-V663. Upgrading from a Denon AVR-1706, I was not sure what to expect from Yamaha. It certainly has a "crisper" and more powerful sound than the "mellow" sounding Denon, which is a good thing considering that my Polk Audio Monitor Speaker setup have silk-dome tweeters which have a laid-back sound. The combo of Polk Audio and Yamaha achieves a great balance in softness and punch, which brings a full-bodied audio experience. 95 watts is plenty of power to drive all of your speakers (My main towers have a tweeter and 4 cone woofer drivers each) There is even an alternative configuration that allows for main channel Bi-Amping.

The sound that this 7.2 Receiver produces when playing a Lossless (TrueHD or DTS-HD) Blu-Ray, is nothing short of thrilling. The only circumstance that I would not recommend this receiver, or any other Yamaha, is if you intend to use a Klipsch Speaker setup, the horn-loaded tweeters mixed with Yamaha's bright sound is a little harsh on the ears. Other than that, this receiver is a must have for next generation audio. The sound from this device is so good, that the next upgrade "step" from here would likely have to be reference grade audio gear, something that would cost a grand or two more, with likely only a marginal improvement. Other higher model receivers feature video upscaling, more HDMI outputs, and slightly higher wattage, not really dealbreakers as far as im concerned.

For Playstation 3 Users,
Keep in mind that PS3 does onboard Dolby TrueHD and DTS HD-MA decoding, therefore the Yamaha will display "PCM" while playing Blu-Rays. This doesn't mean that TrueHD or DTS-HD is not being played, its just being output via PCM. The lossless codec is indicated by checking the PS3's On Screen Display during Blu-Ray playback. You're hearing the exact same thing, only drawback is that the "TrueHD or DTS HD" indicator light will not light up on your receiver, but you get to enjoy these codecs nevertheless.

I bought this receiver at HHgreg for 320 dollars it was a floor model with the standard warranty, so i bought a 2 yr.
extended warranty to make it 3 yrs. I enjoy the the great sound I hear, and with the ease of the HDMI hook up's,in
and out, it was just what I was looking for. I have not used the second room set up yet but I am planning to.The
RX-V663 has plenty of power to kick out movie and music through my Polk, INfinity, and AR speakers, at a great price, happy listening.
