As i mentioned in another thread. i got my uncle a Mac and im slowly ripping his cd collection onto the laptop in FLAC format. and to maintain the best quality of sound, i told him he should get an external DAC. now my question is. ive heard to get the best quality sound, you have to decrease the amount of digital filtering and sampling. so my concern is, since i am ripping cds, which are in 16bit/ 44khz. wouldnt it be better if i get a DAC with the same specs. or should i go with a DAC with higher sampling? my choices are between the Fubar II DAC and M-Audio DAC. both USB compatible.
