OK....I sprung for one of these.
Background : I'm just beginning with CA.....only Itunes till recently ...and I'm brand new to JR MC.
Tired of shuffling discs and albums....
It took a little time, but it wasn't too hard to get the ID working wired and wireless, accessing a host PC.
Took a little more time to get it passing native dsd to a Teac UD-501 dac, but pretty easy once I understood.
I must say I'm very pleased with JR MC, the ID, and the remote android app Gizmo.
