I haven't heard Ashkenazy's Australian M3, but I have a Decca Eloquence copy of his earlier DSO Berlin M3, and I think it's really great. I like it better than the Nagano, which I think is with the very same orchestra. The Sydney M8 is very good, with a real strong organ. I'm curious about his Sydney M7. The M7 Ashkenazy made in Prague (CPO) is quite good.
