DAC output filter...passive or active?
in miniDSP (2x4) board, what is the configuration of DAC output filter? passive or active ?

2x4 unbalanced is passive!

2x4 balanced may be active, since it has opamp at the outputs for balancing the signal. But the actual filter may be passive too :confused:

by sound quality point of view, will active make any difference?

not necessarily ;-) It depends on the actual implementation.

The passive version used on the miniDSP unbalanced works fine ;)

to improve sound quality what mods can be done to existing DAC passive out ckt on miniDSP? if miniDSP is following exact ckt as in ADAU1701 datasheet i wonder if sound can be improved by replacing some components.
