Purchased the RX-V867 back in mid-August during one of the Egg's stellar $399 shipped deals, and finally unboxed and started getting it set up. Key reason for the wait was because I've *still* yet to decide on an HDTV, which btw will be my very first one. I'm not a luddite -- have actively wanted and searched for one for years and years and have kept up with all the plasma offerings (Panny, Sammy, and LG) but only really following Sammy's UNxxDxxxx series for LEDs. Strongly leaning towards the Samsung PN59D7000/D6500, but have been considering the 55ST30 from Panasonic as well.
As for the RX-V867, my two cents on the OSD volume thing. I've been an Onkyo guy since I got the TX-SR602 back in 2004 or so, a receiver I've quite liked but which has absolutely no HDMI whatsoever. I'm doing the fullblown HTPC+plasma deal, and really wanted the simplicity/flexibility of HDMI for most/all of the connections. Anyways, because of the Onkyo I'm quite accustomed to an OSD volume display popping up every time I change the volume (which really isn't that often whilst in the middle of watching -- I usually change it at the beginning of each session).
Now, that said... my beef with Yamaha's OSD volume isn't really the fact that it can't be turned off (although I agree it should be), but rather the fact that Yamaha insists on having that black box behind it as if it were a closed caption. I'm somewhat hearing impaired and thus use closedcaptioning 100% of the time -- the Onkyo's transparent display is much nicer and far less-obtrusive. I like that I can see the volume change on the screen, but it doesn't interfere very much with the show/movie or the captioning that's going on. The Yamaha's black box might make the volume info easier to read but is far more intrusive/obtrusive, interferes with reading the CC, and definitely not appreciated.
It's a mostly minor quibble for me and far from a dealbreaker (I knew it had this going in), but rather than being a "hate Yammy's OSD volume!" guy or a "love Yammy's OSD volume!" guy, I guess I'm more of a "love Onkyo's OSD volume" guy. I like the feature, but want it transparent, not enclosed in a huge black box.
But then, most of us probably acclimate to whatever it is we're using anyways. Give me a couple months and I'm sure I won't think a single thing of it. I'd much rather Yamaha focus on a more modern/functional web interface for the RX-V867, frankly, if they're going to put any real time/effort into what is basically an EOL unit.
I'll post more in-depth thoughts about the receiver as a whole once I get setup finished and especially once a TV has been purchased. Hoping the PN59D7000 drops back down to sub-$1600 on Amazon as it did ~4-5 weeks ago.
