I really liked the SQ of the Classe 800, I haven't heard the others.
I ended up with an Oppo 105 feed into an Emotiva XSP-1 preamp, which sounds just as good, and is 25-33% the price.
That solves the 2-ch music part, and now you(I) can just wait until the HDMI 2.0 processors come out (which you would attach to the Oppo 105/XSP-1).
You need to buy separate separates to avoid the constant upgrading. There is always a new edition of HDMI coming out (they are already working on HDMI 2.1)
You don't want to be forced to spend $6000-15000 every year to keep up with the newest BluRay and TV resolutions/formats in Hi-Fi.
Good Hi-Fi amps, pre-amps, speakers and subs last 100 years. Good old analog voltage.
TV's, processors and disc players are obsolete before they even hit the store shelf; and most certainly 6-48 months later.
But that is sort of a good thing, otherwise we'd still have VHS and 8-Track and CRT cancer tubes.
In 2114 it will be HDMI 99.9, but I'll still have the rest of my same Hi-Fi gear, and all the uber-early-upgraditis adopters will have empty bank accounts and a backyard heap of yesteryears now-useless AVR technology to show for it. LOL
Step 1) Build the best analog LCR + subwoofer system you can: room treatments, HiFi amps, HiFi preamps, HiFi speakers/subs.
Step 2) Don't be an early adopter EVER, unless you enjoy being broke and walking around with a soar a$$ when the new tech doesn't work and is now a beta-version of the technology!
Step 3) Treat TV's, sound processors, computers and disc players like they are disposable trash (because they are).
