Powerful, state of the art AVR: makes my RP 280f's, RP-450C and R-112SW sound fantastic. I had zero issues with setup or updates. I do get an occasional flicker on screen but I imagine that will be cleaned up with the next update. I'm not into speakers surrounding the room, a simple 5.1 is fine.

  High quality, clean digital sound. Simple to setup and this unit has the ability to update for the future

  ONLY 7.1, couldn't at least be 9.1 and with XLR

The Aventage A2A and the A4A so far are the most accessible AV receivers for blind and low vision users.They feature Music Cast for iPhone based control. They also have a browser based installer setup interface that works well with screen reader software.

  IOS application, good remote keypad layout, fantastic audio, good mix of inputs.

• -

  Plastic case, touch controls, usual 45 degree angled feed-points on speaker terminals, accessibility fixes badly needed on IOS Music Cast application.

Improved clarity of vocals, better rendering of instruments, and ample wattage power make my new Yamaha RX-A4A a resounding success for me. Whenever I have made a noticeable improvement in my audio system, I'm a happy consumer, and that's how I feel now.

  Clarity of vocals, instruments and amble power to deliver it to my speakers.

  None that I've noticed

I honestly couldn't believe how much better my music sounded after hooking up my A4A. The vocals and instruments sounded clearer, more realistic, and tighter. The additional power provided more punch to my speakers. I am so glad I bought the A4A!

Was hesitant at first since I'm a Sony man but after having this for a few weeks I really like it. Does everything I wanted an AV receiver to do. I would recommend this for anyone. Only one thing I don't like is the manual could be better. Anyone who buys this will have to play with it for awhile.

We purchased a 4k TV and wanted a receiver capable of delivering the 4k to the TV. I went back and forth between Denon and Yamaha settling on the Yamaha for several reasons important to me.

After a couple of Denon A/V receivers that started losing functionality after a couple of years (dropping inputs, losing the second zone, etc.), I decided to go back to Yamaha which products had provided good value in the past. So far, so good!

I replaced a 6 year old Yamaha RX-A850. I was not sure that this was a good idea until I hooked it up the new A4A. Very happy that I made the switch. The sound was awesome. The listening experience was noticeable. I am still learning how to use the Musicast APP.

Sounds great. Many options and nice interface.

The only issue I have is the it takes Yamaha a long time to release firmware updates.
