Hi Scotty

Make sure that the G68 is not sending out upsampled PCM, as that will exit the unit as MHR encoded and won't work with any other DAC.

You need to set the output in config for the older 18bit DSP5000s as Linnasak noted above, as that will force 1x non MHR output.

You might also want to check from the G68 front display that HS=N instead of HS=Y.

Cheers
