I've been listening to this Zinman M7 a bit more, and I really like it a lot. I think these Zinman recordings can grown on one, as you listen to them more frequently. The rhetoric is toned down a bit, but the musicality of the performances just carry the day. If Zinman had just gone a bit more nutzoid in the back half of the finale, I would put this one at the top of my list. Maybe I still will anyway. He's rather like Haitink in the finale; meaning that he tries to unify some of the tempi through all the little variations, sub-sections, and twist-and-turns located in the last 9 minutes of the finale. But once he gets to the end, there's plenty of peeling bells to suit anyone's taste.
This is why I think of the Zinman cycle as being sort of the modern equivalent of Kubelik's.
