Sounds fantastic and easy to operate
Style: Receiver
I used to sell home audio equipment a long time ago and I love this unit! Nice & clean look, the layout for inputs/output is standard and easy to see and the remote makes sense...well, to me it does lol. I had purchased an O***o unit because it's been good brand for a while...returned it because it was defective but I didn't care for it (you had to be a real audiophile to get into the setup and who has time for that?). The Yamaha is easy to work with and sounds fantastic. Make sure you don't go cheap on the speakers!

Great when on sale
Style: Receiver
Update: I got a new Sony X90L TV and this receiver just doesn't like that TV or something. I've had at least 4 instances where the TV said there was no signal. The receiver was on and the proper input was selected. If I hit the menu button on the receiver, I could see that. No inputs on the receiver would work. Unplugging the power from the receiver and plugging it back in fixes the problem in every case. Based on my googling, many others have similar problems. Yamaha receivers are generally over priced I've noticed. And they seem to skimp on features, e.g. a receiver with an MSRP of $1000 doesn't have a single analog video input. I got this on sale for $650 and for that I'm quite happy. I had a Denon that I got pretty inexpensively, but I hated the Denon. Things didn't work, it was confusing, didn't sound all that good and didn't do HDMI input switching well. The Yamaha is a far better reliever in every way. It does cost quite a bit more but it's just so much nicer.

Modern interfaces, clean sound of Yamaha, tons of features and intelligence.
Style: Receiver
Modern interfaces, clean sound of Yamaha, tons of features and intelligence. Purchased this to replace my amazing RX3300 (it started turning off on its own), and wasn't sure these newer generations of AV receivers would have the same clean and powerful sound, but the RX-A2A did not disappoint. Plus I am loving all of the new features and more relevant interfaces. It provides great value for the price. It is one of the few brands that kept the original sound as natural as possible (of course, there are plenty of modes to choose from for specific characteristics, but only if you choose). Perfect fit for my large family room.

Hours of my life I won’t get back.
Style: Receiver
I tried to make this system work. I REALLY did. Probably blew 10 hours trying to somehow make it work. Had to return it. Customer Support - What customer support? Yamaha cut hours from weak 9 to only 5 hrs a day. Email/chat got no call back. It’s so bad I’m not sure Yamaha is gonna make it. Lip sync - Impossible to fix video to sound lag. Musiccast wireless - See lag. Also sound is tinny as hell. Also won’t stay linked. Could not get speakers to respond to giant volume knob. Would respond to app. App was mediocre. Tried to use with YSP-5600 sound bar which is allegedly Mussiccast. Nope. In short, it has been a HORRIBLE experience and I really tried.

Replacing a RXA770/780/880? You May be Disappointed.
Style: Receiver
I will start with the issues. (1.) HDMI audio drop outs. This can be fix by going into your tv and changing your audio settings from auto to pass through. However I remember this causing an inconvenience of some sort. I did not have to make this change with Marantz M1, Sony AZ1000, Or Integra DRX3.4. (2.) when unit goes into auto-standby while using the digital optical input, it will freeze after turning it on again. I had to unplug it to get it to work correctly. this happened every time. (3.) The plastic front panel can scratch easily. You may want to use a can of air to clean it. Yamaha should have flipped the design-the metal/aluminum where the glass/plastic is and the plastic where the metal is. (4) If using the coaxial for tv audio, It will take 9 full seconds before audio is heard. I had to buy a new TV(this was before the other issues were discovered). Finally (5) if you are replacing a RXA770/780/880, you may be disappointed. You'll have to step up to the RXA4A to get the features like PEQ and menus you had with them. Sound and Power: The 2 channel specs between the Yamaha RXA2A and The Yamaha RN1000A stereo receiver are similar. Don't let that fool you. The RN1000A is way more powerful and sound much better with music, however the A2A was way better than the RN1000A for movies and tv. In full range, sub off, the RXA2A could not drive the Polk RTIa5's well with music. In fact, to me the Marantz M1class D and the Sony AZ1000 70/70w class AB sounded more powerful and musical, making them easier to listen to than the A2A. The Integra best all 3 AVR's for music in full range mode without a sub to my ears. But with the 3.4, the sub output volume was way too low, I hated the click noise(sounds like it powered on again) when turning up master volume, and I couldn't use the presets without changing the source. The Yamaha RN1000a is the best for music only, especially at a sale price. My Positives: It come with a 5 year warranty when registered. It's well built, especially better than the Sony. You get 8 presets that you can set to the same source or different sources almost any kind of way. The dialogue mode works very well even for music. Yamaha Support is very helpful. If yours don't come with the above issues/defects that I listed, I think it can be easy to just set it, forget about it and enjoy it.
