So you want a stereo DAC?
No - I want a multichannel DAC. That's what we're talking about here. I have several hundred 4.0/5.0/5.1 albums in both DSF and FLAC format.
I want to play those back without downmixing as a first priority. I would like a pure USB DAC (I have a mini PC running as a Roon bridge feeding a cheapie, old Denon MCH via HDMI out) with decent specs, a reasonable price range (e.g. without a lot of bells and whistles), a modern OTS DAC chip, that is attainable, which I can build some standalone amps around.
Okto Dac8 Pro is awesome - but it would be good to have one or two more options like that - though given everyone has the same supply chain constraints it might not actually increase overall availability that much.
