Interesting blog blog and test by Archimago. He has identified one of the causes of audible differences between DACs - the filtering methodology used. His test attempts to eliminate this by modelling this. If anyone is looking for an accurate DAC then you really have to read up in detail on the filtering methodology applied, as it really is possible to get transparent filters but it is more likely the manufacturer has used filters as quasi tone controls.
