Modding the PS Audio Directstream DAC MK1 and MK2

We have received many inquires about making the MK1 upgrade even better however some feel that we left them out with the older upgrade.

APS has decided to give our past customers a big discount on the Signature Series PLUS upgrade.

Anyone who purchased our install of the original transformers and Vocm mod in the past 6 months can take advantage of this special.

$1499 TOTAL for our VIP Customers Signature Series PLUS upgrade. You must pay for return shipping as always.

Offer good till the end of July.

Just leave a note in the comments field on checkout. "VIP Customer"

Just a heads up...
We are only able to do 1 or 2 Signature Series PLUS upgrades per week so first come first serve or until we sell out of parts.

We have been asked many times, When did we change over to the new Rev.2 transformers?

Any transformer purchase before December 20/2023 are the older original transformers.

We finalized the new Rev2 transformers on that date. These new R2 transformers allow us to do the needed DC offset tune to increase dynamics and lower the low frequency distortion in our Signature Series DAC's.
