The hardware does not have the limits you describe,
Hi James
I should have made clear that I was talking 'in general'. The card
I bought was some different brand. I don't remember which one.

Hallo Peter,
with which soundcard did You get the result of nearly 60 dB?
Let me guess. That was an example using exactly one frequency. You
can tweak phase an amplitude for -60 dB as demonstrated. But for
real life we need hi supression for a span of frequencies.

. But this is no longer in production.

. But the noise
floor will increase if you widen the filter. This in turn looks bad in
the Hi Fi tests
