Yamaha quality!
Set name: 5.1 Receiver
Excellent sound quality. Easy setup. Complicated audio menus take awhile to master, but once you do you'll be rewarded with amazing sound. Works flawless with my 4k projector and computer. 4 hdmi inputs handles all your audio and video. The auto labeling feature is amazing. I've been using it daily for two years and it performs perfectly. You'll need an external subwoofer amp which is a bit of a let down. I bought one of the small Fosi amps from Amazon that handles the bass flawlessly. Overall, an excellent receiver that will be the centerpiece of your audio and video system. Couldn't be happier. Buy it if you're on the edge of purchasing a new receiver!

It's entry level but it does it great.
Set name: 5.1 Receiver
For what it is, an entry level reciver it is great. Haven't had it long now, about a month but it has been great. Used to own onkyo, pioneer and Harmon Kardon recivers back before HDMI and blu ray. Have used a soundbar for the past few years but finally decided to jump back on a detecated surround system. For my apartment this sounds phenomenal. I don't normally mess with the DSPs so I can't comment on those, I prefer direct sound. Could it use more power? Probably but again this is entry level stuff. I use 12 gauge speaker wire on the front 3 speakers and 14 to the surrounds and it sounds great. Front speakers are 6 ohms and rears are 8 but no trouble driving them. Dialog is crystal clear and the overall sound is warm and pleasant. Playback of Blu ray and Ultra blu ray in both DTS HD and Dolby TrueHD is such a treat, absolutely made me realize how limited a soundbar was. Music playback is fantastic, have my laptop with Jriver hooked up through HDMI for playback of FLAC and WAV audio files from 44khz/16bit all the way up to 192khz/24bit with every genre of music. Put it in direct stereo mode and it sounds blissful. DSD playback does work but only at 2.8mhz DSD64 which is still great considering the price. 4K pass through works as it should, no troubles with HDR or Dolby Vision content. Can't comment on FM or am radio playback. Bluetooth playback is alright, music enhancer does a noticible job of cleaning the music a bit, nothing extreme but does add a cetain clarity. The Bluetooth could have been a more recent standard especially since this reciver came out in 2018 but again entry level. For my Echo it is fine for the rare occasion I send audio to it. Playback of music from LG V60 over Bluetooth sounds okay but wired connection still beats wireless as far as audio is concerned and if you just playing back mp3s AAC, it won't matter, it works. 4K upscale works fine, really didn't mess with it too much because TV is normally going to do a better job of upscalling anyway. Has auto HDCP detection which is nice, allows all HDMI connections to play nice. Binding posts with Banna plug compatibility is nice to see at this price. User interface is nice and simple. One area I can see trouble with is the fact you have to go online for the manual. Again, as a entry level reciver there isn't really much to complain about.

Nice for the price
Set name: 5.1 Receiver, Set name: 5.1 Receiver
Was extremely easy to set up. The automatic sound balancing works good. Sound quality is good as is the surround sound feature. I personally feels it loses a bit of sound quality when connecting a Bluetooth item like my phone. Otherwise, I am satisfied.

Far superior to price comparable Sony receiver
Set name: 5.1 Receiver
I want to compare this to Sony STRDH590, which I owned before this and is of a comparable price. My Sony stopped receiving signal from its remote control within 2 years. There was no way to control many features due to this. The Yamaha has a wide range of buttons on the front if the remote fails.
Now that I have this Yamaha and can compare the sound, this is MUCH better than the Sony. The sound is crisp and clear. This Yamaha receiver has a 5ch stereo expansion setting and the Sony did not even have that. This receiver also has a direct setting that turns off all extra parts of the stereo to attempt to get a clearer signal, including the front panel. The Sony has the nicer input ports (the ones that take the banana plugs) only on the left and right channel where this Yamaha has them for all five channels. The subwoofer output from the Yamaha is considerably better than the Sony and produces a cleaner sound.
The Yamaha setup is extremely easy and takes just a few minutes with the included microphone. So far I haven't had too much difficulty with voices being quiet in movies. There are several applicable sound options for how to process movie input.
The only downsides to this Yamaha are that it only has 4 HDMI inputs and doesn't support eARC. According to the marking ARC is only on the first HDMI input.

Excellent sound and function
Set name: 5.1 Receiver
We're very pleased with this unit. We use a 3.1 system in our TV area, stereo plus center channel and subwoofer. It's nice that this unit supports that. We get very nice imaging from this, and don't really miss the surround speakers.
**We had to replace the old HDMI cables with new ones that could handle the larger bandwidth of 4K. If you're cables are 5-10 years old like ours, newer cables are required to carry a modern video signal.
We like the Yamaha sound, and are able to EQ it easily to sound right for the room. I've used several receivers over the years of various brands. Yamaha consistently delivers good sound and reliable product. I've never had a Yamaha product fail and fewer than 15 years.
There are other units out there with more gadgets and gizmos, bills and whistles, not to mention smoke and mirrors. We want a good sounding reliable unit that plays nice with all of our AV sources and TVs. If that's what you're looking for, look no further than this unit right here.
If you get a good price on this, it's unbeatable.
Sony, Onkyo, Denon, Marantz, etc. - they all make good units with signature sounds. If you aren't familiar with them, and If you can't listen to a bunch of stuff, buy this with confidence.
Here's an unsolicited recommendation: high quality speakers will do more to improve your listening experience than any receiver. If you're looking for an upgrade, start with your front speakers.
