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.

@Jeff: Do you know when the next batch of APS trafos is ready for shipment? Cant wait

We have one pair available now. More to come in June.

If you do trash your analog board, it is not the end of the world. I performed the xformer mod. Difficult to remove xformer without a quality solder sucker. Although I thought it was performed properly, I had some intermittant noise. Sent to PS Audio who replaced the audio board for $300. So it was $300 plus shipping to PS Audio. I was expecting the repair it to be much more expensive. Hats off to PS Audio.

Been letting my upgraded DAC continue to break in when not listening via the USB stick on the PST. Listening this morning and the sound has continued to improve. Soundstage has expanded and image specificity has become more pinpoint and focused. Overall the music has become even more satisfying and intoxicating to listen to, leaving me grinning ear to ear. Thank you so much Jeff for making these upgrades available. Once everything settles in I'll be ordering the shorting plugs. 

Glad you are enjoying your MK1.  The USB shorting plugs makes a big improvement If you are not using that port.
