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.

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.

I hope he will come back one day. The APS Mod for MK2 he did was a great improvement for me."

"None of his posts were removed from this forum other than those which contained personal attracts on others.

Most of his deleted posts were those he personally deleted when he was mad at someone, often one of his customers. I publicly requested he restore them as they were of interest to others. He refused.

We did move his product posts to his dedicated sales thread.

With this clarification we will not be discussing him or any other member of the forum, past or present.

Please feel free to start another thread to discuss mods if interested in doing so."

 

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.
