I'll throw in my vote for the 62 Karajan on vinyl as a complete set, Walter's 3 and 6 (which I think is available on SACD) and the Klieber 5 and 7 noted above. I'm also a fan of the Cantelli #7, and it's one of the Testament reissues on vinyl which is VERY well done.
"Whose" Beethoven do you like?
Between, Klemperer's Beethoven, Karajan's, Toscanini's, Bruno Walter's and Furtwanglers Beethoven, who would be your favorite? I have a Toscanini CD recorded in mono, and i am looking for suggestions on complete set of Beethoven simphonies, that are superbly recorded too! Thanks!
