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.

Following on that, about 2 years ago I had the then new PSA Gain Cell preamp which I found lacking a quality PS. I think the internal PS could be bypassed and a outboard LPS added. Seems right up your alley

Finally, JKRichards admitted that for the DirectStream DAC to sound good, it’s not enough just to swap the transformers and do the simple Vocm mod. You need a good power supply for the analog board.

 

People on the PS Audio forum (including myself) already installed these power supplies 2-3 years ago. And previously, you, Jeff, argued with me that you could NOT hear the difference with the additional power supply vs. without.

 

Now, waiting [another 2 years?] for you to admit that the stock power supply needs to be modified for all these mods to really showcase their best. Because the stock awful noisy power supply is still there in your "Signature plus" version.

 

Here's a free business idea for you. Modify the stock power supply and you will have a Statement version, that you could offer for the price of a new DirectStream MkII .

The DSD DAC already sounded good, before the upgrades, and better after the upgrades. Of course there's always room for improvements, by upgrading more of the internal components.
