[QUOTE="AV, post: 19869, member: 472"] Interesting, although I'm a bit surprised by your measurements. I've checked quickly through the data sheet, it looks like you must select the input format manually, did you change that to 44.1k 16bit when bypassing the upsampler? The AD1955 DAC automatically oversample to 352.8Khz / 384Khz with input freq's from 44.1K (x8 oversampling) to 192K (x2 oversampling). I can't see what the PCM1794 do, if not then upsampling should be better anyway. [/QUOTE]
