"...sorry class D chips are amplifier related. Not dac. I was just curious which dac it was using.
Typical is ess sabre, asahi kasei, analog devices, and many others.
And Hdmi won’t help. As the su6 only uses Hdmi connectors. Has zero relation to Hdmi video/audio connections. The su6 has Hdmi i2s which is a protocol used for sending signal direct to dac. It’s not compatible with Hdmi video/audio. It only sends protocol over a cable. Hope this makes sense. "
