Stopped working

Stopped working after 3 months

Returning it less than 3 hours later

Replacing my 9 year old yamaha, which is still working, but using it as a stereo amp. Onkyo was extremely easy to set-up and get going, in fact it took 20 seconds to do so. But after that, everything is a pain. The biggest one of all is no OSD (on screen display). Coming from a yamaha, i have gotten used to the OSD and the multitude of calibration. The display on this onkyo unit is pretty bad, my 9 year old yamaha is still better. It is bad because of the lack of information / details provided, and the viewing angle means that portion of the screen can't be see (i have mine installed very close to the floor). Going to pick up a new yamaha tomorrow.

Good budget receiver

I've owned this unit for over a year now and I've been very happy with it. It does lack some features you would get in higher end units though. For example, turning on the receiver does not turn on the TV and there's no Atmos capability. It also lacks wifi capability. For some these deficiencies might be a deal breaker. However, it hasn't been for me. Sound is excellent, especially for film. Nice clear highs and very deep bass with no detectable distortion. For a budget unit I would definitely recommend it as I have had zero problems with the unit since I set it up out of the box. I have considered upgrading to a better, more expensive receiver but there really is no need. It drives my Paradigm speakers superbly. Just one caveat though: this is a large AVR so be sure to measure your entertainment unit beforehand to ensure it fits if you're considering buying it. On the whole a very decent product.

Mediocre Sound, Poor HDMI Implementation

First, I’m an Onkyo fan and own two different 600 series receivers. This unit was purchase to replace the older of those two units in a small secondary media room. Consequently, I was willing to sacrifice some soun quality and some features to get a 4k capable receiver. Unfortunately, Onkyo has made the inexplicable decision not to support remote power control over HDMI on this unit leaving one to juggle two remotes. Further, the sound on this unit is just mediocre and the inability to adjust basic set-up options is baffling. It’s going back tomorrow morning and I’ll look for a better-designed unit.

Great sound, easy setup, good features. Everything you'd expect from a modern receiver. Can confirm that it works great with a PC; no video-switching OSD like on the Sony models. 4K60 works great. Note that this receiver, for some inexplicable reason, does NOT have HDMI power link; so you'll need 2 remotes like it's the 90s still. I don't know why they omitted this feature but turning on your TV will not turn on the receiver.

Good and well-balanced

This is probably one of the best low-end receivers you can get for the price; it's got better channel separation and overall sound than the Sony it replaced, and it also handles 4K and HDR10 perfectly with our TV and Xbox One S (once you set the color range settings on the TV and receiver correctly, of course). There's not as many options in the on-screen menu in comparison to the aforementioned Sony (and some functions are punted mainly to the remote and the receiver's display), but the automatic optimization did a very good job getting the speakers configured regardless, and sometimes simple is better - especially in the world of home theatre.

It's OK

I don't have a fancy home theater setup so I opted for this budget receiver. My only real needs were that it supports 4K HDR and CEC. I have an Apple TV and use the Siri remote to control my TV and previous receiver. It has always worked flawlessly and the Siri remote turns on and off both the TV and my previous receiver(also an Onkyo). I replaced my existing Onkyo receiver with this new TX-SR373 and the Siri remote will turn the TV on, control the volume on the receiver but will not power on or off the receiver. No amount of tinkering with the limited settings made it work, so I returned it. If powering the receiver on or off via CEC doesn't bother you then this receiver may be a good choice for you if you're looking for a budget model.

Had to return

Sound was fine. Setup was easy. Discovered after a few days that it would freeze up when fast forwarding my PVR. Sometimes you'd have to wait a few seconds for the freeze to clear, other times you might have to reboot the Onkyo and the Rogers PVR. It got to the point of frequency that we'd just wire the PVR to the TV directly just to get through a show. We returned this unit and bought a Sony which has had no problems so far.

Recieved delivers, nice sound, lots of power, good base..It is worth everything I paid for. Real Cinema Sound. Rock solid performance. Easy to use. A good set of speakers are key to using everything this receiver has to offer
