Hoping to hear from a XP 20 owner if they've tried one of the Mogami Gold db25 connectors as a replacement to the stock db25 with any success.
There was a similar thread on this HERE (since closed) but it was never confirmed if all pins are used for the XP 20.
Pin 13 appears to be open.
I've seen some db25 umbilical cables for Pass and McIntosh with good reviews, and high cost - I have access to Mogami db25 at no cost.
Appreciate any info others may have gathered in this same area.

I found another source that shed some light on the cable used and what is needed if replacing the stock cable.
Another person contacted Pass Labs and was given the data below.
"Here are the specific pins. Multiple Grounds + 8-10 volts for digital power and then left and right analog unregulated at about 40 volts. Pins 12 and 13 are shown jumpered as this is a PCB view. These are separate wires in the cable used for a loop back sense function to keep power off until both units are connected."
