Yamaha RX-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

Fabulous AVR. Does the job, and is sonically accurate. Connects all my 4K devices correctly. If you need more power it offers pre-outs for the main channels for axillary amps. For the average home that's unnecessary. Has good network streaming, a turntable input, and digital FM. The audio environments are amazing for films. The ambiance options are genuine acoustic mappings of actual places. Good for symphonic pieces. Best of you download the manual and have it printed and bound at a nearby copy shop. Let's you calibrate your speakers to the room. Cool

The RX-A4A is very easy to use via either the remote control or the MusicCast iOS app. The front panel of the unit has only two dials (volume and input selector) and four buttons for selecting pre-programmed inputs. Plus front panel connectors for USB and a headphone. Missing is a front panel connector for HDMI which is unfortunate because there are still times I want to connect a laptop to the receiver using my traveling HDMI cable. Now I have to dedicate an HDMI cable connected to a back panel HDMI connection. My previous AV receiver was the RX-V2095 purchased in 2007. That has pretty good audio but the RX-A4A noticeably improves upon that unit especially on the predefined audio and video settings for concert halls and Sci-Fi movie content. Most interesting is the Artificial Intelligence surround sound choice. It does a decent job of determining the best distribution of voice and instrumentation to the speakers based on the source. But I do find I don't like the AI distribution on older audio content that originated from the early days of stereo. Too much of the voice is pushed to the center speaker on that old content which indicates the AI is working as programmed but I'm more used to the 60's and 70's music being evenly distributed between two front speakers. So the best choice, as it was with the RX-2095 was to evenly instruments and voice to all speakers. In my case 7 channel stereo. Otherwise I am pleased with how the AI Surround works. Video management is much easier than the RX-2095 and there is no degradation of video quality that I'm seeing but I'm also not doing any detailed analysis on that. So overall I am very pleased with the RX-A4A. Easy to use and outstanding audio.

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 have been using Yamaha receivers for over 30 years. Recently, I had a 10-year-old RX-A860 die, an electrical surge despite protection; this was a first. I ordered the Yamaha RX-A4A on Amazon, and this may have been the easiest to set up. YPAO appears to have finally worked well this time. In the past, I have deferred to MANUAL SETUP. Although I did tweak it manually as I evaluated the performance. My A4A has a WIRED network connection, so when it notified me of a Firmware Update, all I had to do was click Start. No USB stick required. The menu system was easy to navigate. And these days, if I had a question, Google had the answer on where to find the option in the menu. I also added a Power Conditioner to protect the system from surges.

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!

Right before the advent of HDMI into the zeitgeist of AV I upgraded my entire home theater. I got a multichannel DVD player that would also play SACD and DVD-Audio and a Pioneer Elite receiver that could use its mini-1394 interface. That mini-1394 interface kept me from upgrading for years. I just loved the sound of multichannel SACDs. Then Oppo came out with a multichannel universal player was a little out of reach. Then when I was about to pull the trigger on an Oppo they stopped making their AV components. Well a few years passed and things have changed a little. I still wish I could have gotten my hands on that Oppo unit. Then I bought this Yamaha receiver. One of the main reasons I purchased this unit was the ESS Sabre ES9007S DAC it had. I also had prior positive experiences with Yamaha receivers which helped too. But I first learned of the ESS Sabre DACs when drooling over Oppo components. This as a significant part of the Yamaha component has been amazing. It can play lossless files from my NAS, which has been glorious. And it even does a great job decoding my SACDs fed by my new Sony Universal player. I have also been blown away by how awesome the unit has made films. I viewed The Green Knight, and Dune in the past week and it was incredible. Does a great job processing the Atmos soundtracks into an encompassing experience. I really wished I had made this switch sooner, but it always seemed that my requirements for price and features just wasn't there. But now I couldn't be happier with my home theater's sound.

My RX-V3060 started having video switching issues after 8 years. Time to find a new receiver enter the RX-A4A. This being my fifth to sixth Yamaha I had an idea what I was getting although this was my first replacement do to failure. All my other replacements were due to technology and/or connector/switching issues. The RX-A4A had everything I was looking for to fill our new 24'-16' media room. Sound and speaker zoning was as expected but two things are bothering me. First the set up program doesn't recognize my Parasound power amps (run as mono blocks) and there is no way of correcting this. I am planning to contact tech support about this issue. Second thing the tiny display window that is nearly impossible to read from across the 24' room. These two items if known prior to purchase would have killed the deal and I would have gone with the Denon. I use the A4A for a 5.1 plus Atmos and twin 10" subwoofers. The set up program doesn't recognize my twin Parasound power amps or twin subwoofers. The power amps allow me to run two sets of front speakers (Klipsch RP=8400F and vintage B&W B&W DM604 S3 floor standers) again these should be recognized in the set up speaker array. The Yamaha has loads to power and can bring the Day of the Dead scenes in the James Bond Thriller Spectre to a wall crumbling collapsing end that will shake you homes walls!

I have used a few different brands and models, and couldn’t be happier with this YAMAHA RX-A4A. Awesome sound and power. It delivers crisp and clear sound with the punch that you need for home theater. I love the PURE DIRECT mode that delivers the power you need for karaoke. You have to spend a little more to enjoy the music and audio experience. I tried the RX-A2A and that does not have enough power and the sound is not to my expectations. I highly recommend this YAMAHA RX-A4A for your home theater and music listening. At least the RX-A4A or A6A.
