Great replacement to my older 5.1 Yamaha receiver.
Style: 7.2 Receiver
Great replacement for an older Yamaha. My previous unit lasted 10 years and I see no reason why this new one wont last another 10. Familiar features and setup to other Yamaha receivers. Zero issues with setup and contrary to others, you can use all the features without the app. While the app does add some features for streaming, the unit is fully usable as a receiver for movies, surround, etc. without the app. Overall the sound improvement is spectacular, the high slew rate really makes a difference and DSP much improved over the older 10 year old unit I had. Solid hardware, solid setup and while I'm not about Brand Loyalty, the Yamaha still had better features, reviews and quality than the other major brands. I would have no issue recommending this to unit to anyone. Remember, these units are about the sound they offer, not the the wiz bang features you see in some other units. Reliable hardware, reliable sound and a rich feature set makes this unit a no brainer.

Great receiver for money!
Style: 7.2 Receiver
I got this to replace my lackluster Onkyo TX-NR6050 I purchased from Costco. Three areas stand out for me with the Yamaha receiver:
1: Audio, movies sound great, dialogue is clear. Action scenes are impactful and dynamic.
2: Picture quality, bright, vibrant and beautiful colors from my PC and from my Firestick.
3: Ease of use, out of the box ready to go. Menu is dated (no gui really just an overlay, which is fine by me). Renaming inputs, adjusting speaker settings and setting EQ preferences super easy. Took about 20-25 minutes to fully setup. In those 20-25 minutes I was already way ahead of the Onkyo.
Great value for the price! Volume is very easy to set!
Still have to test PS5 performance, Bluetooth connectivity, USB settings, WiFi and a few other items. I’ll probably end up buying a Blu-ray player since this was so easy to setup! Or maybe use my PS5/Xbox One :)

Solid 2 Zone Receiver / Amplifier - Excellent video and Audio
Style: 7.2 Receiver
I purchased this Yamaha to replace the 10YO previous version that no longer decoded SiriusXM. This new clean front panel design and much improved remote control are easy to use once installed. I have to say the only complexity I have run into is connecting 3 smart devices together - NVIDIA Shield PRO Streaming Box, RX V6A Receiver and LG OLED TV via HDMI chain from Streaming to Receiver to TV with no audio or video passing through the TV first. The only issues that result is getting all 3 to play nicely when switching on and off via a single (NVIDIA) remote control. It is nothing short of fantastic to be able to have such a simple remote control all three devices for the most common functions. Only specialty settings require a specific remote. However it becomes an issue of chicken or egg - as control messages to go on or off are carried by HDMI and the power sequence becomes complex - with options to turn on or off IF ... THEN... for all 3!
Otherwise the receiver has been a dream to finally restore sound to several rooms in our home from SIriusXM and now several other sources as well, I'm thrilled with the features, new MusiCast control and ease of operation once installed and properly paired for single remote operation. I plan to have this around another 10 years and enjoye the excellent 4K video upscaled by the NVIDIA device and handled beautifully by the receiver to drive the TV in rich color and great 5 Channel Sound.

A great A/V receiver at a great price. Too bad Amazon Customer support is horrible.
Style: 7.2 Receiver, Style: 7.2 Receiver
Pros,
1. A 7.2 channel A/V receiver that can do 5.1.2 Atmos. It also support DTS-X as well.
2. 200 watts total power. Don't let that fool you. It powers my 5.1.2 speaker setup far better than my previous Onkyo TX-NR5100 that's supposed to 80 watts per channel. Also sounds a lot better and clearer.
3. 7 HMDI inputs and 1 HDMI eARC output that support 8k/60hz and 4k/120hz with Dolby Vision. Additional speaker inputs for extra zones for run into other room.
4. Uses banana plugs for easy installation.
5. Has both WIFI and Bluetooth. Also includes an AM/FM antenna as well as a speaker calibration mic.
6. Has two RCA subwoofer input jacks for dual sub units.
7. Very well built and very sturdy unit. Looks very nice.
8. Includes an extremely nice remove control.
Cons,
1. It's not the easiest to setup nor the most user friendly. Once setup you should be good, but it's a matter of the learning curves.
2. Make sure you get the latest firmware. You may get unlucky, get an older unit, wonder where all the features are at and why they're not available.
3. Lastly Amazon customer support is utterly horrible and useless. I order this produce and later that day they offered a discount. I called up customer support for a price match and THEY REFUSED TO DO IT!!!! I ended up canceling the order and reordering at the better price and Amazon ended up losing money because they were getting ready to ship the first order. LEARN TO PRICE MATCH LIKE YOUR COMPETITION!!!!!!!!
I have this hooked up to my computer for movies and gaming, it works great because of the 120hz pass through. Other than horrible customer support the receiver is great and otherwise I'd have rated it a 5 star. I took one star for the customer support.
