Enable 24/96 ouput for CAL CL-20

Does anyone know how to enable the 24/96 output for the California Audio Labs CL-20? I would like to try out some higher bit rate formats.

I would contact Allied Audio in Litchfield, CT. They were the east coast repair station for CAL. However, it may require a software update.
thanks I'll try that
any luck on the 24/96 up?
