Bioman, I agree with you. Without naming names, some DG reissues came to mind in my second post about the Penguin guide. Older DG is better. I have not cared for too many of those "DG Originals" CDs that look like an LP. I have some I like for the performance only.
London/Decca overall are quite good; and for historic, the "Decca Legends" and "The Classic Sound" are well made. For Bernstein fans, I find those newer "Bernstein Century" on Sony an overall improvement from the older "The Royal Edition" (which are OK as well).
I agree with those who like the Mercury Living Presence historic, and the RCA Living Stereo.
