Modding the PS Audio Directstream DAC MK1 and MK2

Below is a Post by Elk on the PS Audio Forum. He can’t even be honest with the forum members over there. He knows I can’t post on the PS Audio Forum to correct false information.

He did in fact delete any post that praised our mods and / or post that showed any flaws in their product and how to fix them since the new MK2 was launched. As a matter of fact, PS Audio is currently using my fix for the latest FLAW the dreaded input grounding clips.

The last one was the one I posted here on this Forum.

I have many screenshots to prove all of this.

He even locked down the modding topic after this was posted.

The weird thing is we have tripled our sales since leaving the PS Audio Forum and opening the website.  Should have done this a long time ago.

Here is an FFT of our modded MK1 with our nickel transformers.  Much better than the stock unit and the new MK2.

Interesting; however, the mkii sounds better than the mki.  That’s my listening comparison with both having the edcore transformers (no other mods).  Will hear the APS transformers in the mkii soon enough.

That may be true however without the Vocm mod and our nickel transformers in the MK1, it’s not a fair comparison. We have both the fully modified MK1 and the MK2 with our transformers, the input grounds fixed and 3M RF shielding setup to do instant blind A/B comparisons and most who listen here cannot pick a winner. They are that close. I can pick the MK2 most of the time however I know exactly what to listen for not necessarily the best sounding. They are both great sounding.

Hands down the build quality of the MK1 is far better than the MK2.  We are pretty disappointed in the build quality of the MK2 since we have been modding many of them here. Every one of them have / had build issues.
