I am thinking about upgrading my Yamaha RX-V1600 to the Yamaha RX-V663, RX-V863, RX-V1900 primarily to get the HD audio formats. The first mistake I made was buying the RX-V1600 about six months before all HD audio formats or HMDI 1.3 became widely available/affordable. I’d like to not let this happen again. I want this next receiver to be my receiver for the next 10 years or so.
I do like my RX-V1600 for the power, preprogrammed surround programs, Pure Direct (though I don’t use it much), and generally I think it is a solid receiver. I also like Yamaha receivers in general, but have seen some nice Denons. Listening mix is 70% movies / 20% games / 10% music.
My current setup is:
• Sony Bravia 1080p 52”
• Playstation 3 (games and movies)
• Xbox 360 w/HD-DVD attachment
• Front Floorstanders – Klipsch RF-52 (100W RMS)
• Center – Klipsch RC-52 (125W RMS)
• Rear Surrounds – Klipsch RS-42 (75W RMS)
• DefTech SuperCube III powered subwoofer
• DirecTv HD receiver
• Panamax power conditioner
• 2 to 1 HDMI switcher
Please let me know your thoughts on the following:
• Is the audio difference in HD audio formats noticeable?
• How is the selection of preprogrammed surround programs on the RX-V663 and RX-V863?
• How much power do I need sufficient power my speakers, particularly the fronts? (this is perhaps my biggest determent next to the difference is HD audio format)
I like the RX-V1900 because of the overall features, setup versatility for the future, and clear front face (i.e. the sliding cover), and the audio prick in me saying it simply looks like a bad *** receiver.

I had to be honest about that part. In to the future I hope to have a dedicated home theater room but nothing high-end. More than likely a basement or family room that I can retreat to.
I will either sell my RX-V1600 or hold on to it for a future spare room receiver. I can’t imagine its worth much without HDMI 1.3a.
Any advice is greatly appreciated!!!!
