Premium sound quality
Wao. This is amazing
I am extremely satisfied with the Yamaha A8A. It delivers excellent sound quality and offers a premium Hi-Fi listening experience. I previously used a Denon 13.2 receiver, and the Yamaha not only measures up but surpasses it in many ways. The sound is outstanding, and I am very impressed with its performance. Overall, I highly recommend the Yamaha A8A for anyone seeking a high-quality audio receiver.

Quality and reliability included
Powerful upgrade to my modest home theater
I had an a4a and wanted to upgrade to 5.2.4
Having the ability to adjust subs independently is the biggest difference I noticed immediately and made a huge impact in balancing my sound
Paired with a emotiva basx A3 to take the pressure of my front stage I couldn’t be happier with how dynamic this setup is
I tried a Denon 6700 and didn’t like it. The Yamaha has a backlit remote that lights up just by picking it up and pass through works great so with the unit off I can use anything attached to it with headphones or tv speakers without having to wake the family

Unreliable and may have NO WARRANTY
Unit has failed. It won't power up. Blinking red light. Called Yamaha and they are verifying the 3prd party through Amazon is a authorized dealer prior to authorizing repair. Less than 2 years old. Home page on Amazon sales screen advertises it comes with a 5 year warranty with registration. How would I know if or if not Amazons vender is a authorized dealer? I'm going to be you know what if they come back and say NO WARRANTY. I will update as the process moves along.

The same convoluted / painful User Experience as existed in the 1980s
I hadn't purchased something like this since college so I assumed it would be a radically different UX (user experience) regarding setup / functionality. Nope. Getting the device to actually play the audio I'm hoping / attempting to play is a constant battle. (Certainly partially due to my incompetence and also the horrible projector software I'm using (BenQ - atrocious software). I'm sure after I've owned the Yamaha for 5-10 years I'll get the hang of it but it would certainly be nice if these incredible systems could communicate w/ one another (i.e. "hey, there's a signal coming in from Device X - I think I'll hide all dormant inputs so it's less confusing..." Annnyway, the sound is absolutely fantastic. I'm thrilled w/ the quality of sound every time we use it. After my anger fades because I just spent 20-30 minutes trying to get sound to output for the movie / game / show we're attempting to watch. Yes, I'm a grumpy old man. You will be too one day.

Mostly Satisfied, but a little let down!
I am upgrading from a Yamaha RXA-870 which is still a great amp and I love it, but wanted the ATMOS with 11.2 surround... The RXA-870 has a far superior Web App to where you can control so much ore. The A8A has a lot of control, but seems to be missing the Web App to better control the Surround Sound, The A8A seems to be more automated... I am also having issues where when I calibrate the speakers it continually gives me a message that there is a wiring problem with my Right Speaker, but nothing is wrong with the Right Speaker... When they say that it take 45 Minutes to update the software... They are not lying.. Downloaded to USB and Updated via USB... and it took 45 Minutes... It was flawless, but not as fast as I was hoping. When they say this unit is heavy... they were being 100% truthful... I had to get a neighbors help to set it on the shelf that I wanted it on.. and if you put it on a shelf... IT HAD BETTER BE HEAVY DUTY! -
