Dave - sorry I misunderstood. So you are talking about out of band aliasing artifacts over 22.5k at the output of the DAC? These would be mostly captured by an ADC running at 96, but not by an ADC at 44.1... I was only thinking of in-band. I haven't tried comparing 2 DACS using this method yet. The only DACs I have are the one in the SB, my MF and the ones in my 5103. This will be interesting.
