I've been curious about the Karajan M9 for years, but I've found it a bit pricey. Anyway, this time I ordered it, got it on Monday and have listened to it a couple of times. And, yes, it is truly excellent. If I didn't have access to any other M9 recordings than this one, I could live with it. Thank you, Barry, for re-reminding me of the Karajan M9.
PS His recording of dLvdE with Ludwig and Kollo is also worth listening to.
