No official model number / product name yet, I'll add a link to the final product page once it's available:

It came with ultra-low noise voltage regulators as well other tweaks for delivering clean power to the board, definitely targeting the audiophile market with that Oven Controlled Crystal (Xtal) Oscillator.

The same seller also designed this "audio grade" 32GB eMMC (i.e. different from the "ancient" stuff called MMC) with the regular SDHC form factor, most likely his customers would also purchase that instead of going for CM4 with built-in eMMC storage:

@starchivore - I may be missing it here, but is the idea to use a USB audio interface with this?
