Digital filtering isn't really needed for 96kHz playback (as indicated in the impulse response chart in the link)..... A good analog filter would likely render the music more naturally..... These "brickwall" filters were originally intended to attain full audio bandwidth (20 Hz to 20 kHz) for CD playback, sampled at 44.1 kHz..... (The "brickwall" was needed because Fs/2, 22.05 kHz was very close to the top end of the established audio band, 20 kHz. Analog filters needed to be very high order to achieve this. But this issue goes away with higher sample rates.) For full audio bandwidth with music sampled at 96 kHz or higher, I believe a "soft" analog filter would likely work best, with no oversampling.
