I forgot to add the MK2 with the Antero firmware. It's also a "10"
In modded form, We feel the MK1 and Mk2 with the above firmware sound almost identical.
No one here could tell which DAC was playing.
Modding the PS Audio Directstream DAC MK1 and MK2
I would like to continue discussing all the mods we have created for these two DAC's as it seems PS Audio is no longer allowing discussions about them on their forum.
For reference here is a link to the closed discussion.
