There was a thread started on this subject when the box set was released. Although there was not a large number of responses I think the general consensus was the new issues were, for the most part, a significant sonic improvement.

After many listens I can concur with my original recommendation that the box set is very much worth owning, but I was making my comparisons between the new set and my original LP pressings. I cannot address the comparison between the box set and "other reissued LP's of his".
