Not really understanding the technical descriptions above, I never really thought that Blue Note albums were anything special, audio-wise. My idea of a good sounding LP was something on Columbia (the Byrd/Gryce "Jazz Lab" album comes to mind) or maybe Capitol. And of the jazz labels, Contemporary. (With Argo being the worst.) But I'm talking late '50's-early '60,s, with a Heath Kit amp and a Garrard (sp?) table, I could be all wet on this.
