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

Second time around , kinda

This is the 1st time I bought a Tonewinner product, but it has the same DNA of an Emotiva Basxmc1, with some significant differences.
My Basx was great, but with bugs. I heard this Tonewinner version was better, and Emotiva is turning their Mc1's into receivers. And my new Monolith Amp having Fake balanced inputs I went with Tonewinner.
My system is 7.2.4, and the logos on the balanced connections are a little hard to read, but I got it right the first time. It's locked up once, but that is probably the memory getting full while I was trying the SD card reader. No big deal. I set the distance and levels and put in my disc of Top Gun Maverick.
And was blown away. This unit sounds amazing.
More Atmos presence than the MC1. A wall of sound. Overall the experience is smoother and easier than my other unit. It hasn't been "Americanized" but that is no big deal. That one freeze episode was the only instance so far.
EARC works fine and that's important as I don't have cable and need my TV audio for streaming.
The entire process has been smooth sailing , helped by the fact that I already have experience with another version. Being an Audiophile my system is hybrid, with home theater bypass, but I could see running some audio sources through this unit.
It's that good. Great for someone who wants HT without having to sell a kidney. Unless you want Dirac and other niceties I really can't see spending more money'. Or maybe you just want to stick your toe in the water. Or maybe you figure that any kind of separates is better than a receiver. Which is true.
Wish this little unit was around when I was starting this hobby. A serious processor at this price point?
With balanced outs? Amazing. The bugs on the Mc1 were fixable but not a lot of people have my experience. And you shouldn't have to deal with things like that. And with this Tonewinner you shouldn't have to. Now let's check this card reader again...
