I ordered this, along with a DB25 snake and a/b switcher to test alongside my current setup, for the time being via the Volume8.
Hoping the switcher doesn't degrade the quality even more than the volume knob, which crackles when I turn it!
The AES inputs on the Dac8 Pro would actually be better for my purposes, so maybe this release will alleviate some of the demand pressure, or perhaps even free up existing supply
In the meantime, I ordered a used RME ADI-4 DD, which should allow me to complete the chain for HDMI sources (HDMI switcher -> HDMI to SDI converter -> SDI to Audio 4K converter -> ADI-4 DD -> Digiface USB -> Mac mini -> DM7 or back out to Digiface + other DACs).
I can't tell if things are getting simpler or more convoluted, or both.
