Today a PS Audio technical service technician posted an advisory regarding modified DSD Mk II DACs (latest iteration). Apparently they have had more than a few of these modified units come i for repair. The nature of the repair was an output transformer swap. PS Audio is not saying what transformers were installed, who did the install, or if the installation was sub par. These units are failing all PS Audio bench tests and the repair is a replacement bard with the original style transformers installed. As the affected units have been modified the repair is not covered buy warranty. A link to the thread provided in the PS Audio Forum is provided for reference:
