Very happy.

Excellent service and delivery. Works as advertised. Exactly what we needed. Thank you Summit-HiFi.

Amazing Device - But beware the software upgrades.

I purchased an AT-300 as a reference source for music mixing in my new Atmos mixing studio. The XLR outputs make the 300 a natural fit in the professional recording studio infrastructure.
Please be careful with the software updates and DO NOT USE the software from the ToneWinners site. Use only the software posted at Summit HiFi. I did not follow those instructions with the first AT-300 they sent and I bricked the unit. Thankfully, Aamir at Summit was diligent in helping me troubleshoot and eventually replace the unit. The new one is working great and is now an invaluable tool in my studio.

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.
