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.


The Nickel laminations are running late. There seem to be a shortage of this material now. Also, the price has skyrocketed. Unfortunately, we will have to raise the price of all our transformers. Current pre-paid orders will be honored. The new price will be $799 for a matched pair plus shipping for both MK1 and MK2. The wait time for the Nickel lamination’s is currently 12 - 14 weeks. We will only accept orders that are pre-paid which means you will receive your transformers about 15 weeks after payment is received.
Sorry… This is out of our control. We will NOT obtain lamination’s from outside the US as there have been reported issues with authentic 80% nickel material from other locations

Glad I jumped in before the supply chain issues kicked in. 

Any updates on the 8139 opamp modification?
