Sorry, but I have that set, where does it say that it was 20-bit K2 remastered, I don't remember seeing that printed anywhere. Not that I'm doubting you or anything. :unsure:
Unless there was a Japanese only release of this one;
then I don't think this set was 20-bit K2 remastered, mine says it was done by Kirk Felton in 2000. I think you might be mistaking it for the Bill Evans Complete V.V. set, which was 20-bit K2 remastered.
Either way it's a great set.
Mine was a Japanese set and it was 20-bit K2 remastered. I don't remember exactly (I sold the set ages ago), but I think it said so in the booklet. And no, I'm not mistaking it for the Bill Evans set you mentioned.
Musically it's a great set indeed, but, as I said earlier, to my ears sonically my set was not.
