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.


Was browsing this AM and found this hack job.  This maybe worse than the first one posted.  At least he is not selling this for retail.


Vocm mod 🤣


Going to give the person some credit. First, they used nickel core APS transformers. Had the right idea on the Vocm mod, just the execution of not using suface mount and creating antennae. The added structural support for the capacitors is creative. Likely sounds good.

Must have been a difficult decision coming to the conclusion of no longer offering APS transformers for the MKII. A real loss for the MK2 community. Hopefully, when PS Audio gets its production issues sorted, you may consider revisiting the decision. 

Spent a day revisiting the Snowmass 3.0.5 firmware in my Vocm APS xformer modded MK1. In my system, in my acoustic environment, and my ears I prefer Sunlight. Just my experience, YMMV.
