    • Excellent amplifier.

      from Mississauga on May 29, 2019

      This is an excellent amplifier for the price. I have used it with retro Sony speakers that I had for 15 years. The same speakers sounded better. Blue tooth is not easy to connect but once connection was successful, it worked flawlessly. The treble and bass adj work nicely. This is my second onyo receiver. Had another surround for HT for 4 years now. Both are great

      I just got this receiver today thinking it would be a good buy from the reviews I read here. Pretty disappointed in it and will likely return it. Played with the controls to try and make it sound acceptable but just not up to my standards. It sounds muddy to me if that can be an audio term. Should have known by the cheap price that it would be cheap sounding. My wife doesn't mind it but she likes lots of bass. It does have that. Over saturated in bass for my like. It you turn back the base it sounds totally bland. I was going to place my old 25 year old Denon with it because it is a surround sound unit and I just wanted a 2 channel to play records on. The Denon kicks it ass. This is the first time I have bought any Onkyo product. It will be the last time. I figured in 25 years things would have gotten better . Guess old school still rules in audio.

    • meet all my expectations for the price
