Well. . . I'm not sure that my thoughts will help you; I like the trio albums best. Largely because. . . well I love piano trios, and Pullen was such a unique talent that I love his being so richly presented in the trio format. AND. . . I"ll put on my heat resistant suit. . .a little bit of Adams goes a long way with me. I really DO like his work, but I find myself tiring of him sooner than I do Pullen.
So. . . I listen to the trio albums more. I haven't heard many European trio albums from Pullen, so I can't really compare them.
Sonicwise. . . I think there is some improvement in this new version, but the original cds didn't sound horrible, and I wouldn't buy this just for the sound.
