Is there an OP amp in the DSD DAC? If so this OP amp Danny is talking about sounds like it would be worth upgrading to.
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.

The opamps in this Directstream DAC are special high frequency video opamps. The ones Danny is speaking of from Sparkos is a replacement for standard opamps (not compatible at all with the DS). We make our own discrete opamps for other equipment. We have tested other compatible opamps however the ones in the DS work the best especially when the DC offset is fixed. We have spent 1.000’s of hours working with the Directstream MK1 DAC and feel it’s at it’s best with the Limited Edition upgrade. We even tried using a custom opamp output stage instead of our transformers and it didn’t sound even close to what have now. Ted designed these DS DAC’s to use an audio transformer for a reason. |
