Yeah, you mentioned it to me as well!
I saw the website but haven't tried it. To me, I don't like the idea of a plugin or something processing my music, as far as Im concerned an amp or pre amp should do that sort of stuff and it should be permanent, I.E on a recording.
I'm not sure how it could make compressed audio sound much better without doing some EQing and maybe losing further detail...Mind you I just got a dac magic (Cambridge Audio) and apparently that does "upsampling" which is supposed to improve quality somewhat. How it works I have no idea but it sounds fantasically detailed in terms of non compressed audio
