Digital Link DAC mods?

Are mods still available for this DAC? Such a solid piece and it sounds good, just not refined in its stock form (at least by todays standards). Thanks!

Rick Cullen did a mod and those units come up for sale from time to time. I think he is/was associated with wyred4sound. Maybe check there? Also his son owns Cullen Cables, maybe he has some insight into where you can look. I found this contact for Rick, don’t know if it’s accurate.
