After researching on processors with great reviews on AT-300 from Tone Winner and other audio/video sites. Arrived in a well packaged box and in perfect shape. Thank you, Amir! Will return and write a review after completed home theater project.

Excellent product

"Combination of Tome-winner AT-300 with TW AD-7300 2.0 is a game-changer! The sound quality is top-notch and the sleek design adds a modern touch to my entertainment setup. Easy setup and seamless integration with my smart devices make it a no-brainer. Highly recommend to anyone looking for an outstanding poweramp with pre-amp.

Great AV Pre Amp

I spent so many hours researching pre-amps, and am very glad I made this purchase. I really wanted something with XLR that was easy to use; after deciding 8k was more of a marketing tool than something I needed, I was between this amp, Emotiva and IOTA. They all seem to be made by Tonewinner, and I quickly crossed Emotiva off the list since they have no XLRs and have not push any updates to the unit since release. Then between IOTA and TW it basically came down to price. The Tonewinner is about 20% off the price of IOTA (plus could not find a good local distributor).... in addition, Tonewinner has so many updates and are supporting the system. After a call from Aamir, and his incredible customer service I purchased the unit along with the new 11 channel TW amp. Both have been amazing. I think auto EQ would be much better if it took multiple measurements and aggregated them by speakers, so I would avoid it for now. The pre-set EQ are great I have found, but REW worked just as well.


I went from a Pioneer SC-85 AVR to the AT- 300. Set up was straight forward and fairly easy. I also went with OSD amps to make my system budget friendly, I have had no issues with the processor or the amps at this time. Customer service is great, received a call shortly after placing my order to let me know the status - later I had a question about setup and was informed I could contact them after hours if needed (I figured it out without needing to call).
