Yes - interesting contraption - I didn’t see anything about cost though.
For me personally I would much rather use my own ADC as I already have a great phono pre-amp in my A-S2100 amp and my turntable is already connected to it and so I would just connect the pre-amp’s rec-out to an external ADC (current have an RME UFX on there which is part of my studio system) and then it will work with whatever source I am playing.
I already have Roon extensions to deal with input selection and volume control on the amp. Roon integrated ADC is the missing link
This use of component of choice rather than having to deal with someone else’s choices is another of the reasons I like Roon over other multi-zone media player systems.
