Chord and several others before them are making big noises about their
new DAC's which claim wonders due to the use of a filter designed by
someone called Robert Watts, he calls it a Watts Transient Aligned
filter. Other than on Chords pages, or related adverts/review sites I
can find no mention of this alg on the web at all, and neither can I
find anything in the IEEE library. Does it ring a bell with yourself (or
anyone) or is it just more BS?

There's an 2006 thread on the prosoundweb forum, but the discussion
diverges into dithering. Err, a discussion of dither.
