Modding the PS Audio Directstream DAC MK1 and MK2

Here is three of the five we compared.  The stock units are gone.

Can we purchase APS stickers like the ones shown above? You installed the Vocm and your nickel APS transformers. I do not consider it a DS anymore and would like to have a way of showing. Sent same message on your website.

Hello Guys.

Has anyone used silver bearing conductive adhesive instead of solder for the caps  with the Vocm mod?

There are some very low resistive ones to chose from and easy to apply without the danger overheating the SMD. Durability does not seem to be a factor according to the manufactures data sheet.The adhesives are not cheap but neither is a new board.My most concern is with sound quality.

Thanks .

We started using these badges on our signature series DAC upgrades where we fine tune the DC offset and use the newer revised transformers in the MK1.

Using a preamp, we feel Firmware fpga1_208_Antero or the first fpga1 228 Massive sound better. The new fpga1 233 Massive is clearer and can have more detail and a larger stage however for us just doesn’t sound as "real". Just a little thin sounding for our taste. String instruments have lost their body and texture.

Hi Jeff. Was this evaluation done on a MkII with your trafos, or a stock unit, or both?
