Just a heads up. We only have one complete unit available now and are down to a few transformers. We won't be making any more till next year.
JK Richards PS Audio DSD MKI transformer upgrade
I sent my PS Audio DSD MKI to JK Richards to be fitted with the upgraded nickel transformers and VOCM caps. Should be arriving today. Will follow up with a comparison review once the upgraded DAC settles in.
Here is a link to the lengthy thread covering the evolution of the PS Audio DSD mods.

Here is the layout of components of our Limited Edition Signature Series PLUS units.

We have received a lot of interest in making the bridge 2 card sound good in these MK1 DAC's. We have been working on it for a few weeks now and have it almost completed. One of the biggest problem with these Bridge cards is the fact that they draw a lot of current and it uses only one stock regulator. This is why units with the Bridge card installed, the power supply heatsinks over heat and literally burns the rubber coating on the transformer wires and discolors the heatsinks. The underside of the lid gets stained and smells like burnt rubber where the wires leave the residue from the heat. Not good. We discovered this is one reason the Bridge 2 cards do not sound that good. You will need at least the Signature Series PLUS upgrade. You will have to send your unit in to have larger hestsinks installed and an additional discrete 5v regulator, a new post regulator capacitor installed along with your Bridge 2 card. Running it through test currently. Cost is will be announced later. The first few will get a large discount. |
