If you are as knowledgeable as you make it out to be, you will know that a 3-pole active filter is not necessary from 20k. There are manufacturers who use much slower slopes for better sonics. In this sense, the EMU is band limiting. I would summise that this is for spec reasons, to cut out hf artefacts.As for digital filters, there are filters and filters. See dcsltd.co.uk for white papers on how these affect the sound.

If you can't, then you are either lying, or don't know what you are talking about, or both.PS - I hope you realise that the number of poles does not indicate the steepness of the filter. You are confusing between poles and orders I think. In any case, measured data shows that the frequency response is +/-3dB to 48kHz for a 96kHz sampling rate I fail to understand exactly where the bandwidth is limited, except at Nyquist.
Why do you think that people lie. Perhaps this tells more about yourself.
Let's see ...1. You claim there is an "extra" filter, but cannot or will not show us where this filter is located.
2. You say the output is "bandwidth limited", yet measured results say otherwise.
Why do I think you are lying? Gee, I don't know ...
Furthermore, you confuse between filter slope and the number of poles in a filter - two unrelated concepts.
Can you give us one reason why we should even pay any attention to anything you say in the future? Otherwise, it's time to move on.
