Another Winner from Aamir/Summit Hi-Fi

Had a great experience with Aamir and the Summit A7 so...I bought another one for my home theater system (first one went in the game room). I'm using this one to drive (2) sets of front L&R + C + front heights. Since I already had 2 Emotiva A2's and (2) outlaw M2200's I decided I didn't really need the Emotiva MR1 any longer for amplification so I wanted to try a separate processor. That's where the Tonewinner AT-300 came in. First observation was is was immediately clear when I opened the interface that TW makes
the processors for Emotiva.

The next thing was the remote. I was concerned the remote wouldn't have all the individual trim functions. Concerns alleviated. It has MORE control.

Next...the microphone. A MUCH nicer mic setup than anything I have used to date. XLR mic and a REAL TRIPOD. Fantastic! Also of note, since I was already familiar with emo's gui, it was super easy to set things up. At first I just set up the 5.2.4 layout manually/by ear just so I could enjoy and movie the first night. Today I used all the mic-driven auto tuning functions and the levels were spot on for the most part to what I did by ear. What I didn't do by ear was the distance and eq functions. Ran those today and the distances are also spot on. Pretty amazing. I run (4) different brands
of speakers (I know). The eq did a great job leveling things out. I would have had to spend a good amount of time doing that manually.

Trigger and CEC controls work flawlessy. Every time.

As another bonus...the unit itself is also quite attractive.

A few improvements I would like to suggest:
-Larger on unit display. When in eArc mode it's tough for these old eyes to see from 4.2 meters away.

-There are some "emotiva-like" ticks when searching for audio format, but not as noticeable and easy to make less apparent by reducing volume before switch program sources. *To be fair I noticed this in an Onkyo RZ50 I tested also

-OSD/User Interface...looks I designed it

-The phone app is a little klugey but does work. Mainly an appearance consideration.

-The whole package could be "more Americanized. I'm sure that's coming.

If you want to dip your toes in the separate processor level of the hobby, this is the way to go, no question

Really looking forward to the next iteration of the TW processor.

Amazing performance for the money . It has a little learning curve compared to other brands but when I started really learning how it works it started to seriously impress me with its sound quality . It seriously punches above its weight. I have been comparing it to a Marantz av8805 and it is holding its own against it , maybe even surpassing it in someways. Also Amir is great to deal with and is really helpful and knowledgeable and most importantly honest. He is making it possible for people that could not afford separates to get into them without spending huge amounts of money. I look forward to dealing Amir at summit hi if in the future and will strongly recommend him and the products he sells to others. It was an excellent experience.


I have had a great experience with this company.
Thank you for extra time spent for my order.

scott claason
great processor!

I now have more expensive processors sitting in the closet
because the have been replaced by the at-300


Excellent product and amazing service from Amir who called me twice to help equipment connectivity. Thanks very much!
