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.


Today a PS Audio technical service technician posted an advisory regarding modified DSD Mk II DACs (latest iteration).  Apparently they have had more than a few of these modified units come i for repair. The nature of the repair was an output transformer swap.  PS Audio is not saying what transformers were installed, who did the install, or if the installation was sub par.  These units are failing all PS Audio bench tests and the repair is a replacement bard with the original style transformers installed.  As the affected units have been modified the repair is not covered buy warranty.  A link to the thread provided in the PS Audio Forum is provided for reference:

Look up Weedeewap.  See the real reason these units are failing.

This hack job is why.


I would know first hand if even one unit failed that we installed transformers in.  We have had none fail. They must be talking about someone doing a self install of some others transformers as we only sent out (2) two pairs for self install.  One has already commented here. The other is still going strong.

We did turn down one unit and refuse to install which had this hack job done to it.
