hi what's the best settings to use when connected to a dac, drc on or off etc thank you
If I understand the electronics correctly (and I am no expert), using the optical digital out option means all of the X10 / X30 electronics are effectively bypassed. Assuming that is right, I can't see how the DRC setting can have any effect when the optical out is used. This means the combined work of your external DAC and (presumably?) a separate amp will be responsible for the tonal "sound" rather than the X10 / X30.
If I'm wrong, hopefully someone can shed some more light on the matter.
As an aside, another thread (last year) seems to suggest DRC makes little difference with the current firmware and set up - search for "DRC".
