Modding the PS Audio Directstream DAC MK1 and MK2

Here is our new assessment.

“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 7

Stock MK2 with new firmware 8

Modded MK2 with new massive firmware 9

Modded MK1 with Snowmass  10"

OK... We have only 3 pairs of MK2 cores left and will not be offering them any longer after they are gone. 

Wow this is too bad.  I'm trying to convince a friend with a MkII to have the transformers installed.  Maybe once I get mine back and hear them I can convince him.   

I forgot to add the MK2 with the Antero firmware.  It's also a "10"

In modded form, We feel the MK1 and Mk2 with the above firmware sound almost identical.

No one here could tell which DAC was playing.

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 🤣
