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.

Hi Richard, just curious what you think of the modded MKII with the latest FPGA update,  compared to the modded MKI? I know before you mentioned that the MKII  was only slightly better.

We feel the new firmware made a large improvement in sound quality.

If I had to put numbers on it from 1-10

Stock MK1 6

Modded MK1 9

Stock MK2 with old firmware 8

Stock MK2 with new firmware 9

Modded MK2 with new firmware 10

Thanks for your input. Was entertaining the thought of upgrading to the MK2 and having it modded with the nickel transformers and caps. Seems like it's not a huge difference though, plus after reading through posts on PS Audio's forum, many are continuing to have issues. Perhaps down the road, if and when PS Audio irons out the many glitches, I'll reevaluate
