I guess the gentle slope would provide a better impulse response (linear phase and no ringing) but there may remain some (little) aliasing / imaging.
Sometime I'm dreaming of a 192kHz AD/DA with bessel analog filtering cutting off gently at say -3dB @25kHz... Does no designer build such a converter?
There are several filtering options for both PCM and DSD. The filters affect how upper “out-of-audio” band frequencies are rolled off.
Sharp – Brickwall cutoff at ½ sampling rate.
Slow - Gentle cutoff with some aliasing.
Cutoff frequency – 50, 60, or 70 kilohertz cut off.
Gentle Filter to reduce high frequency noise.
"Played around with the PCM sharp and slow filters, Sharp seems to bring my system to life." Mytek Stereo 192 - Page 24
"For filtering you can choose between sharp and soft and indeed that's how the audible effect is perceived, but the effect in this case isn't very large (...)" hifi-advice.com - Mytek stereo 192-DSD DAC review
As always the best way is to hear it on your own.
