I bought two of the HTR-765 this evening, I've setup one of them in my bedroom so far. It's replacing a Yamaha RX-V2600 that's I've had for years.
Pros: Smaller! I no longer need a piece of plywood to support the front legs of the receiver. Remote is lighter but smaller capacity batteries. Layout of the remote is more intuitive, scenes are good, and its nice to be able to select inputs without names. iOS app is very nice! The speaker setup with the mic was simple as usual for Yamaha, sounds good. Using my second stereo speakers as presence up front was cake. AirPlay works fine. There are pre-amp outputs on this receiver, dual sub outputs. Price was right, Costco beats others by a good $100 or so!
Cons: No slaved power plug, my sub stays on as a result and I hate the slight hum! The power plug isn't socketed. No album art with AirPlay. The remote doesn't light but then my other Yamaha remote doesn't either just the one this replaced. The manual came on a CD, no paper. The receiver shows up in the iOS app and AirPlay as a serial number, I'm hoping I can name it as with two this will suck. Display is a brighter white than I'd like, the other was a dimmer yellow. Overall the power plug is the part that sucks most, I think my sub downstairs triggers on signal inpu but not this onet. I may have to upgrade this one :-(
That's it for now. I didn't see any threads on this receiver specifically so I figured I'd provide feedback. I'll post more as I use them and find quirks. Oh, mine apparently came with up to date firmware. I'll say the setup screen sure could look better too (shrug) but its functional for the little I've used it so far.
