Thanks Paul for the feedback. Are you excluding the option of 2 slots + wifi so that Tidal and other streaming services are supported? This is really the combination I am chasing. I use 200GB sd cards, but because I store uncompressed music and also High Resolution Audio, one slot is simply not enough.
Pioneer XDP 300R has 2 microSD card slots and supports Tidal perfectly.
SQ wise, it's nowhere near the DX200
