I've made my decision. While my main concern is audio, the fact is I'm buying a receiver, a key component in my video watching. So, I can't pretend as if I am just investing my ideal audio set-up. I have been persuaded to look towards the future and buy a receiver that is capable of handling the latest HDMI and HDCP (or whatever it is). I started this thread saying I could be talked into $700 or $800. Well, that was a madman talking. If I were sane, I would have spent $450 or $500 on a receiver that is nicer than any I have had. Instead, I'm compromising with the madman, spending just under $700 after shipping.
For just a bit more than that price, with the help of a kind soul, I could have bought a brand new Marantz 5011 that would done everything I needed it to do--it even had the 7.1 analog inputs that I had placed so much weight on. Despite the fact that I was happy with my Marantz SR7004, I decided that I was already crazy pushing the $700 mark, and so would not go over it (the line must be drawn somewhere, I guess).
Instead, I have bought a receiver that does not have 7.1 analog inputs, but does have all the new HDMI connections and can process the new fancy audio formats. I have purchased the Yamaha RX-A1050. I thought it would be nice to try a new brand. But what really swayed me was...THE FIFTH FOOT:
Anti-Resonance Technology Wedge Helps to Ensure that Vibrations Do Not Affect Sound Quality
The Anti-Resonance Technology Wedge is a fifth foot in the center of the unit. It dampens vibrations from the power transformer, power transistors and heat sinks, as well as vibrations that might be caused by the sound from the speakers.
