I just got one of these too… US$922 from ShenzenAudio they gave me a 10% belated Black Friday/cyber Monday discount - so I couldn’t resist… local agent had no stock…shipping was free too.
@spockfish It works at full native DSD512 on the Ropieee.org OS too which is great.
Not yet tried on ROCK/Nucleus but im guessing Windows will only work at Native with the driver installed and MAC maybe DSD256 -all of course via USBA-C cable - be sure to get a cable that supports DATA, not just a charging cable!
One grip is the diabolical wifi password keyboard interface - otherwise pretty impressed.
Screen is too small to across a room but for HP listening its adequate.
only used with 1/4" headphone out thus far, but will try XLR/RCA out at some stage.
