Yamaha TSR-7850R 7.2-Channel Network AV Receiver

First off. Fully aware this was a re-furb as, currenty, CLEARLY stated in the listing. Can't speak to what it, the listing, may have said previously. Super happy so far. Arrived fast. Well packed. Factory-box packed inside much bigger AMZ box with "padding". (it was sliding around a little), one of the 4 inner styrofoam end-caps had busted up a bit but still immobile within inner box.Key Item points: (pros)1.) Refurbished by Yamaha. (not AMZ or other 3rd party) Factory sealed Yamaha box.2.) Appeared new. not so much as a finger-smudge let alone a ding or a scratch.3.) Original remote? YES. The listing includes the disclaimer: "Box and accessories may be generic". SO I was holding my breath on that little, especially ref the REMOTE, but, Accessory pack was ALL new. Sealed Yamaha Original.4.) Really appeared brand new. There were just 3 ways you could tell it wasn't new. The box. Yamaha but generic. 2. no protective-adhesive clear plastic on the front of the unit. (yet it was crystal-clean not the slightest nick or smudge). 3. on the back, pasted over the original serial number was a small sticker that read "refurbished item" and under that a new serial #.5.) I set it up in about 10 minutes. 5 speakers + sub, two HDMI devices IN, HDMI out to TV, (never cracked the printed manual), power on: Video and Sound, 5X5. Good to go. OPTIONAL Personal preference-tweaking via-remote/on screen menu took longer but it was ready to rock without that. IMPORTANT: IF you don't consider yourself "experienced" I DON'T recommend skipping the manual. I comes with a (new) printed manual and you should set it up with that in hand.6.) Right off the bat-(10min-in) Sound was better than the econo-grade Sony this was replacing. Upon Parmetric-EQ tweaking, sound was MUCH better. (= to or better than my Aventage 830) Video I swear was better. The Sony had the most current HDMI standard, this was at least = to if not, it seemed 1st-DVD, better.I did not use the "YPAO" auto-adjust for the speakers so I can't comment good or bad on that. I do manual. The test-tone is a big help in highlighting which speakers need more or less. Levels are super easy. EQ is optional. Sounds great out of the box. If you care the manual (7-band) parametric EQ is feature-rich to say the least. A little intimating for a novice I think. the good news is you can HEAR what what's happening in real time as you change things. (have something playing). When you hit the options menu the playing-video will be partially or fully hidden, but the audio is unaffected.7.) Network, connecting to my wireless router was super simple. sub five minutes. (never touched the manual) 3 or 4 minutes after completing this the unit spontaneously prompted for "firmware update available". which I let it do. Said "up to 20 minutes to complete" it was closer to 5. No muss no fuss.I DO have some Bluetooth devices... ain't played with that yet. I could "SEE" my desktop PC on the wireless router but getting IN to it was not no-instructions-intuitive. (access denied)Cons:1.) The remote. Not a biggie, but I liked the two-tone silver and black one that came with my Aventage 830 MUCH better. This one is ALL black and in the dark it's a lot harder to tell what's where. The GOOD news is the old remote works on this unit!. ("Aventage" is Yamaha) so by sticking with Yamaha I now have a back up remote.2.) The only other con that's sticking out to me at the moment is the USB input can't be used for Video-from hard-drive input. OR if it can it would be only on a stick, (like 128gb-ish-or-less), no "real" external USB HD's. I connected a 1tb drive and got "no device" or some such.so FAR no issues with the "HDMI" board another reviewer was going on about. As I previously commented on his review, before I bought this, I googled what he was talking about and got essentially 0 hits.Will update if this fails in weeks or months to come.So far I am happy ears-guy.
