Yes, but the question is: are they outstanding because they are
fixed point, or because they have been designed well generally,
with the fixed point aspect just being marketing ?

A few years ago there was a very large scale listening test
(involving hundreds of 'trained' listeners), comparing the
quality of 'HD' DVD-A and SACD recordings reproduced directly,
and the same recordings reduced to CD quality. There's an
engineering report about it in the AES library.

The first result was that essentially nobody was able to
identify which was which.

The second result was that most listeners actually preferred
the HD recordings to CD versions of the same music, same
performers, but not he same recording.

That seems to be a contradiction, but it isn't. The simple
fact is that those HD recordings, targeting a specialist
audience, have been made with much more care and expense
than the average CD. They are actually better recordings,
but *not* because they are 'HD'.

I'm pretty sure something similar is involved with e.g.
the fixed point filters you refer to, and a lot of similar
things. Just going for quality doesn't sell things, because
most people won't hear the difference. But adding a bit of
pseudo-science helps, in particular if a large part of the
target audience has no technical or scientific background
anyway and is not capable of separting facts and fiction.
