oh ok! well many external DAC are called "NOS", but when you read the DAC datasheet, it's usually 32 or 64X oversampling.
upsampling is no good, it only increases THD+N(easy to measure w/ SineGen+WaveSpectra).
but even the manufacturer of the DAC that is used on the ST sort of recommends to use 128X for 44.1 and 64X for 96KHz....default is 64X for all rates.
and whatever the several audio engineers I've talked to, or this url I posted above seems to be saying that the more you oversample the better the filtering and the less aliasing you get in the end?
ideally if Asus could let us choose it in the drivers, that'd be awesomeness. I'll discuss it w/ my contact there
