It does not.  The mods only work with the MK1 Sr.  
JK Richards PS Audio DSD MKI transformer upgrade
Many months ago we set out to make the outgoing PS Audio Directstream MK1 with upgrades to the transformers and circuits, sound better than the "new" $8,000 PS Audio Directstream MK2. We finally did it with our Signature Series upgraded MK1 DAC. ... 
Modding the PS Audio Directstream DAC MK1 and MK2
We finished our last MK2 transformer install yesterday. Wow... Many flaws. All digital boards standoffs were completely loose. The bolt that holds the power transformer was not even tightened. It was moving around inside the case. The i2s inputs ...

Here is the real reason the new MK2 is failing.  It is filled with flaws and QC is awful.  From the flawed grounding tabs to screws crossed threaded and many never tightened. Loose power transformers and many adapter boards hand soldered makes for... 
Modding the PS Audio Directstream DAC MK1 and MK2
We are very excited about our new Signature Series Modded MK1 DAC. Before the new mod the DC offset averages between 3.6mv and as high as 12mv. No unit we ever received here was below 3.6mv. Most were about 7mv or more. With our new DC offset tun...

Modding the PS Audio Directstream DAC MK1 and MK2
I overlooked the reason some didn't think Snowmass 3.05 sounded better than other versions. We revisited this with the original Rev.1 transformers and the difference between the firmware is very close. We feel Windom or Sunlight do sound very goo...

Modding the PS Audio Directstream DAC MK1 and MK2
With our nickel transformers and stock. To us it sounds like a fake top end and lack of low/mid dynamics. We like fpga1_208_Antero best. We also feel that both the MK1 and MK2 needs a preamp to sound it’s best just like most other DAC’s.
