    I ought to add, that listening to WTA filters above 16FS (different tap lengths, different oversampling) does have different sound...

    So the area of the error relates to the sample rates - so a 768kHz signal would have 256 times less transient error innately, expressed...

    About a year ago I looked into that very issue with new filters. There have been some small benefits, but as you get higher in frequency...
