Default Comments regarding "phase distortion" correction?

Having not seen a comment about addressing this "problem", if it is one; Would anyone be willing to voice an opinion about the Taddeo Digital Antidote 2?

I've seen it recommended by a few on other boards but some critical examination of the of the circuit and it's effects would be interesting.

When you start with a false premise ("brick wall filters at 44.1", hey, find me one of those players!), peddle a solution that doesn't take into account the different, nonstandard filtration done in different CD players, and market your box as "the most important audio component except for you ears," what do you have? You've got hype and BS, that's what you've got.

If anti-imaging filtration had been standardized for the CD, a phase correction filter might have a chance to work- though it would be FAR better to implement it digitally on the source end, with zero cost to the end consumer. But there is no standard, all CD players are different in that respect, and the audibility of these "phase shifts" is somewhat questionable, anyway.

Complete BS, utter nonsense, don't buy it, etc

I really like when he interprets a half sampling period delay as phase distortion Ridiculuous
