At higher sampling rate, the filter is much less colored, and I canít really find any meaningful difference between filter types, can you?
My DIY valve DAC has a function to facilitate blind listening to various different filters: a steep linear-phase filter, an apodizing filter that is almost linear phase in its passband but not in its stopband and a linear-phase halfband filter. I never used it, because I don't even hear any difference when I know what filter is selected, not even at 44.1 kHz sample rate. No matter what filter is selected, there is always headroom to prevent intersample overshoots and the passband ripple is dominated by a filter that is always in the path (the interpolation filter of an SRC4392).
