YamahaRX-A4A AVENTAGE 7.2-Channel AV Receiver – 8K and 4K/120 HDMI, eARC, Dolby Atmos, DTS:X, Auro-3D, Surround:AI, Wi-Fi, Bluetooth, MusicCast

It's a Yamaha, it just works. I've been buying Yamaha ever since getting burned by no less than 4 Onk0 products, one Integra and three Onkyos. HDMI boards in each went south.But enough of that, this is a Yamaha review after all. HDMI switching is as quick as you could want, sound quality is very good, and I have very revealing speakers with RAAL ribbon tweeters. I don't really care for the 24 or so sound effects stuff Yamaha includes in most or their AVRs, but it's no big deal since they don't get in the way of what I want, which is nice clean sound. And that is where this Yamaha shines.What I don't like is that great big volume knob on the front of this thing. Couldn't look more ridiculous if they had pasted a big red rubber clown nose on it! All to hide the fact that they cheaped out with that itty bitty display window that is difficult to read without binoculars!

This is my second one of these and after listening to mine a good friend bought 2 also (one for living room, one for basement home theater. I use my main one as a pre-amp and digital music processing system to push a 5 channel 300 watt per channel amp to listen to HD FLAC music and the occasional movie. The built in DAC is not the best but is perfectly acceptable for critical listening. I have compared it to several external DACs and it compares favorably. The music processing is very good especially the "All Channel Stereo" feature. It's heavy and well built.I recommend this receiver for anyone that listens to music as a primary activity.

The Yamaha Aventage RX-A4A is a quality built, well engineered AV receiver packed with a plethora of digital sound programs to enhance your music or movie experience.

I’m a Huge fan of Yamaha and own Many Yamaha receivers. They are usually relatively easy to setup and have great features and sound quality. This unit is the first model that requires a USB flash drive in order to update the firmware. The process is tedious and frustrating and would be impossible without Computer skills. Once you download the file you need to unzip it and then place the .bin file on a formatted USB drive. Then you can install the firmware. (Currently version 2.21)When you get that done you can go through the process of setting up the system which requires making changes in many different screens and it could be confusing to some people. Once it is set up properly it sounds fantastic. It can upscale to 4K and has Many options for sound processing but it’s tricky to get the show on the road. Some people are going to be frustrated. I don’t recommend using Ethernet cable … use WiFi instead.Yamaha claims wired connection works but it seemed to me that the unit choked on the wired connection. It’s a terrific sounding receiver and a good looking device but the quirky setup keeps me from giving it 5 stars.

I picked this up for a really good price. I've been needing to upgrade for a long time. My RX-V3800 has long been due to be replaced (although, it makes a great second amp.) I'm not going into much detail as you will find in the other reviews and I will likely amend my review once I have more experience with unit.Setup was pretty straight forward. The unit out the box was doing some strange things with the eArc (and still kinda is, more on that in a bit,) but most of the issues were resovled after a firmware update.I know others have mentioned weird/anamolous issues with the communication of different manufacturers equipment via the HDMI and eArc. I have experienced this, too. My audio does not always sync with what is being played. Sometimes there's a 5-10 second delay from start of video to the time audio starts. Other times, there's just nothing. It's highly variable and some streaming apps perform differently. What I'm trying to determine is if it my TV/AVR interface (or maybe the streaming apps on the TV) or the A4A itself. I never had this audio delay with the RX-V3800 (granted not an eArc device.) Quickly using the Google-Machine, I found that my issues don't seem to be unique, but my home theater setup is definitely unique to me. I have not reached out to Yamaha yet, well, because I want to eliminate my known variables before pleading for help. I've tried all the obvious culprits with inconsistent results. It almost seems like there might be more than one interaction contributing to the audio issues.I don't want to make a full judgement on the this unit yet since I'm not certain there's not some strange interaciton between equipment and/or apps.So, I'm giving this unit a 5 star to start. It performs really well when the audio is pushed out correctly. MusicCast also works well. It's just the quirky thing with timing. I'll amend this review with my findings at a later date.EDIT: I was able to solve my issue. Since my initial review, Yamaha pushed out another firmware update. The update didn't solve the issue, but I noticed that the delay became more consistent and repeatable. After perusing recent reddit posts I started looking at my TV audio settings more closely. I changed my digital output format on the eArc from Auto to passthrough. My audio went crazy, but thought I'd restart the entire system to see what Id get. Whaaaalaaaa! After reboot the system worked perfect. I hope this helps someone and saves them some (painful) time. It tuned out not to be an exclusive issue with the A4A. However, there has to be some standard that makes the devices play well together. Whatever that is, someone didn't follow it.
