Tonewinner AT-300

I am very impressed with the unit. It's a great upgrade for my home theater. Aamir from Summit HiFi, he is the best... he helped me with the purchase of the unit, and he was very patient with me. They have my 100% recommendation!!👌🏻

I am impressed

This purchase was a bit of a gamble. I needed a solution for my Dolby Atmos setup. I use Adam Audio powered speakers through a Focusrite interface. Having a processor with balanced outputs was very appealing. I had read good reviews online and decided to take a chance on the AT-300. The Tonewinner unit comes from China but it was delivered quickly and I was able to track it.
Setting up the unit took some time and I had a firmware issue. I decided to contact Aamir for some help and he replied immediately at 11PM!! He was very helpful and quickly sent me a firmware update that fixed the problem. So far the unit is working great. Sometimes I get a hiss from two of the channels but could be from the signal coming in. A reset fixes it. The sound is excellent and it handles the Dolby Atmos processing flawlessly. I use an Apple TV 4K to feed the eARC HDMI port.
Overall I am happy with my purchase and recommend SummitHiFi and Aamir. Thank you.

Mostly fun and games

This prepro is capable and easy to use. Running sound from earc to at300 has had its growing pains figuring out that it freezes if settings aren't changed to not output to both hdmi out ports and only to the non arc hdmi out. Also read remak 6 about the remote. WTH. ( ; overall I'm really happy with the at300 and the part that I had issues was solved easily by talking to amir. I wish all my tech support expiriences were this quick, effective and honest. I mentioned that usb PC audio wasnt working and he immediately agreeded and said updates are coming for it. He also had a solution for the at300 freezing up. I spent the rest of the day fine-tuning and setting up and the results have been pretty incredible.

Auto Room Test

I couldn't get the Auto Room Test to work due user error. I simply didn't have the thing plugged in all the way into the jack on the back. You really gotta hear it click on this one. That's a good thing. Anyway, Aamir helped me through thick and thin making sure that I got it figured out and I thank him. This guy really is as good as everyone makes him out to be. Just you see. The processor itself is awesome. I come from a Denon like most people. The difference is amazing. There's a powerful detail and clarity that you just have to hear to understand. Don't hesitate. Just buy one. You'll see.


Just delivered yesterday got it hooked up and working. Have not calibrated yet but it sounds great so far. I look forward to what it will sound like with movies when I get it fully set up.
