You see some of their music selection above. These are the two I heard:
Limehouse Blues by Arne Domnérus. http://shz.am/t56034103
This was a 176 Khz high-res track and it sounded good.
In A Trance by Anthony Jackson, Simon Phillips, Hiromi. http://shz.am/t309513996
Another digital track played by Playback Designs' Merlot DAC. It was a DSD track. It sounded flat, likely due to very dead room. See all the absorbers above, combined with curtain, floor carpeting, chairs, etc.
