Questyle QP1(r) Digital Audio Player

Questyle QP1r High resolution digital audio player. Please search the internet for all of its features, but the best thing about this player is its sound quality. Has slots for 2 micro SD cards, so with 2 cards it can hold lots of DSD files, or an almost infinite number of FLAC or lower resolution files. I just had it sent to Questyle in China to be fully updated, including a rubber coating on the center wheel for smoother operation. COMES WITH LEATHER CASE that is normally a $60 option.  PayPal only.  Here are the specs from the website: · Memory: Internal: 32GB
