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.

These MK1’s are hard to beat. We will also reconsider making another batch of power boards. Our break even number is 5 boards at $300 ea. This is a plug and play solution that will allow you to use the internal PS or the external one. If no external PS is hooked up the unit will use the internal PS. If the external PS is hooked up then the External PS will be used. It will be automatic and also will pass the power to the analog board at the correct time during power up. This will be a card that slides in the Bridge port with the external power supply connector and LED indicator. All one needs to do is move the analog PS plug to the new board and connect the supplied cable to the analog board. Kit will include the cable with the 2 pin connectors for the external power supply and the DSD.
This is what everyone will receive. 
It’s very simple to install.

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. |
