Maybe it's OT, in case feel free of delete it.
As my quest for a simple lossless file reader continued even after the rude "coming off the scene" of the M50, I'm currently having some spass with this little thing Aiyima
does , eagerly waiting for new year wage bonuses aiming at getting a DMP-A6.
Just USB-SD inputs so no streaming functions, I2S, BT or digital transport at all.
Files are processed via an AKM4490 DAC chip, sound is output via RCA, coax or optical and, have to say, it's pretty pleasant.
The good news is that it reads -everything- you will throw at it and that (maybe) it's USB-flashable for possible FW updates.
The big, big gripe is that this player is not gapless,
so what it means about enjoying your music collection is to be carefully considered.
To make things worse, it doesn't work with CUE tags for ISO files that are read entirely. Gulp...
Not a charming thing as the M50 was, as you can easily see, but at least it's a little lossless player I can play with.
