...or 192kHz, digital filters can be much more gentle over a wide spectrum (less steep) well beyond the audible spectrum. Such filters introduce far less time smear and are less harmful."This is only true if the source material itself was sampled at those higher frequencies. (DVD, SACD, etc.) If the resolution is not there on the source material (redbook CD), it cannot be recovered or re-created. If you applied a "more gentle" digital filter over source material sampled at 44.1 kHz, the end result would be the "images" (frequency reflections of the signal below 22.05 kHz) above 22.05 kHz making it out of the DAC, not more resolution.
