The sound quality, CPU efficiency and interface ergonomics are perfect.
The only strange thing, as to me, is that in Dynamic Phase processing mode (which in fact is dynamic EQ mode) equal damping of adjacent bands result in non-flat amplitude response (significant peak at crossfade freq. is present). Seems, this is not an immanent feature and maybe can be corrected (e.g. using two consequent symmetric low- and hi-shelve filters with same 'significant frequency' result in flat response, even if not it always can be corrected by realative frequency shift).
