Sorry, I hate to be the one dissenting party. Though I only bought M2, M3, and M10 from the Zinman cycle as "cut-outs" from Berkshire Record Outlet, overall, what I heard left me cold. The overall sound captured the hall quite well, but inner orchestral detail sounded blurred. And Zinman's overall approach to performing Mahler was something that I felt I could sleep through. M2 and M3 are in my "discard/sell" pile, but I kept M10 for the particular performing version (I think it was Carpenter's).
