yes, I think lcd can display more infomation, but need more time to finish.
Optical and coaxial accept 96kHz/24bit and usb 48khz/16bit.

Sweet would love to test that thing out! I would run it 8+ hrs a day every day in place of another amp.

I like seeing the temp as I bet its showing temp near chips and in a case is a good thing to see.

Thanks for your suggestion.
We use sta320+STA50x as power DAC.
I will improve the lcd view. The LED is build-in so I can't change the color now, but I will use 2 different display later.

The temperature sensor is included in MCU, so I just don't want to waste it.
