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.


Another funny post from PS Audio forum:

Also the thing with measurement, If I have a predetermined bias before hand, I can make the measurement results to support the said bias.

I’d take any audio measurements with a huge grain of salt unless the methology is published and can be verified by an unbiased party.

What??? How ridicules is that?

Why don't you ask for the manufacturer to show measurements that demonstrate otherwise? If manufacturer can't or won't do that, then that is that and independent data remains as authoritative.

PSA just posted their measurements.

Yes they did. SINAD at best would be 70 dB. Same as what we posted last week when I was accused of posting bias measurements and badmouthing PS Audio.


Unbelievable... It took PS Audio forum members over a week to discover and discuss this problem after my post exposing this issue was deleted by Elk. The ones who have the tabs missing or loose... This is not an easy fix as they rip off the copper foil when they come loose. All units I have worked on here had this issue. Even brand-new ones that have just shipped. I knew it would eventually catch up to them and be exposed and many questions asked by unhappy customers. PS Audio should have done the right thing from the beginning instead of trying to hide the issue.
