I've had the tonewinner AT-7300HD for about 3 weeks now. I've paired it with the Tonewinner AD 7300 PA+ power amplifier and my Cabasse baltic5 front stage / Cabasse i03 surround speakers and 4 x Bowers and wilkins PV1D subs. Set up was straight forward and easy to do I used the XLR balanced connections as these provide a cleaner signal pathway when compared with unbalanced connections. Coming from an all in one AVR to separates I wasn't sure what to expect. After set up and after running the tonewinner room correction programme, I have to admit that sonically I was impressed. The sound stage was more wide and dispersed than what the AVR produced. The Bass was tight and controlled. The midrange pronounced and clear without being overly bright and the upper register clear, concise and attenuated. Whilst not the most intuitive set up UI, it does the job given it's basic nature. If anything it was easier to navigate than it's more modern counterparts. Connecting my audio visual peripherals to the AT 7300 HD was a breeze. This is where the simplicity of the UI set up interface really came into its own. You're able to delve into a multitude of settings for each connected audio visual piece of equipment. HDMI switching between sources is fast and stable without any discernable lag, although initially the signal from my 4K TV (loewe) would inexplicably drop and the AT-7300HD would indicate no signal status for that particular source. After many hours trouble shooting and researching the issue online. I once again delved into the tonewinner manual for this product. The issue was the CEC functionality built into the AT-7300HD. Tonewinner suggests that this should be disabled to avoid strange behaviours like I was experiencing. Once done I've not had a repeat of the dropped signal. The remote control for the unit works well and without issue. Nothing fancy and does the job. There is an app which can be used. Connection is via Bluetooth. Whilst connection can be tedious and a little hit and miss. Once connection is achieved the app works flawlessley. The build of the AT-7300HD is superb. All aluminium chassis with glass front display panel. It matches the aesthetics of the AD 7300PA+ beautifully. It's understated and simple design stand out. It's operation sublime despite the occasional querks. If your looking for a processor that is affordable and operationally and feature wise punches above it's weight. Then you owe it to yourself to give this unit consideration.
