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.

Great processor and above all great experience with Aamir

Always had integrated AVR and always tempted to go with separate pre amp and power amp.
Never found anything that would convince me 100%. Than one day I discovered Tonewinner and a lot of people really happy of their experience with Aamir at SummitHifi.
Decided to give it a try. I contacted Aamir to know more about the at-300 and the ad-7300pa.
Talking with Aamir made me decided to go with this products.
Had a couple of small issues but I was so pleased with how Aamir has been always present and responsive.
Summithifi it’s really one of a kind. I have 20 years experience with home theater related products. Had shopped from many different stores but so far Aamir really is above all.
Now, about the At-300: quality it’s really great. I had top of the line Avr from Pioneer and Marantz but this one seems to be better than them so far for the Atmos or Multichannel content.
It seems that my subwoofer has a better response than before.
Again, so far I’m really happy of my decision to go this road.

Upgrade from denon!

I recently made the leap into separates and wow!! At-300 + the 7x300 amp from time winner is excellent.. Aamir is an excellent guy to know and is a online call away for any questions or issues.

So I ran denon receivers for years and watched many reviews on separates on you tube and decided to go with tonewinner as it did not break the bank, and is affordable. The detail I got is just amazing, the surrounds are crisp and clear with detail for days. The subs are tighter and have a little more punch than before..

If you are starting out please contact summit hifi!!
