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.

That’s great to hear Jeff, but now I’m wishing I held off a little longer before sending my DAC off to get modded, so I could’ve had you do this latest upgrade as well.

Hopefully I can find someone locally in the Denver area to perform this mod.

Will the whole DAC need to be sent in, in order to have this mod installed? 

are we able to purchase the op amp upgrade parts and instructions when available?
