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.

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

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!

It's a little rough. Receiver came with update 1.10. Doesn't seem to be compatible with my Nvidia Shield at the time of this review. Wouldn't playback content that had both Atmos and Dolby vision on my LG Cx or my Shield and sound would cut out every 5 minutes or so.

Awsome receiver, is reacing my 20 plus year old yamaha.

Tried to make the RX-A2A work with my setup, but really wanted the preouts for more than just the Front/Mains on 7.1 setup.After doing more research on the A4A, I found that the A2A is not really on the same level as the 4,6 and 8.Not just power, but in construction and design.

  Yamaha design and quality; construction is well thought put and executed5 year warranty availableMusic Cast is a nice app for streaminge.g Spotify and Airplay work wellAbility to customize setup and sound

• -

  Cost high, relative to competitors feature set.Setup was fairly unpleasant, and there are some clumsy navigation and setup functions.Be nice if you could eventually use an app on your phone to perform settings that currently need to be set with the your TV on.

I've had this receiver for about a week now after returning the Onkyo TX-NR6100 due to it lacking in sound quality. The Yamaha RX-A4A definitely matches the quality I was used to with another Yamaha receiver prior to trying the Onkyo model.

I just connected my new RX-A4A and upgrade for my A1050. Everything seems to work great with the exception of my DVR. I have a Xfinity X1 Box that worked great with the 1050 but with the A4A the sound kept muting.
