I have the M1 USB with all the latest upgrades (purchased April 2013) and upgraded it for DSD. I agree with Lasercd regarding the analog like sound of DSD played through the M1. I use a Bryston BDP-2 for PCM, PC laptop with J. River v19 for DSD and a PS Audio PWT for CDs (rarely use it). I'm anxiously awaiting Bryston's implementation of DSD output capability for the BDP-2. Bryston has stated that DSD output upgrade for the BDP-2 should be out before the end of the year.
Back to the M1, it sounds great but I've only compared it to my PWD mkII. I have a lot of DSD files and they sound so musically engaging through the M1 and my Harbeth M40.1 speakers.
