I've tried hard to like this set, being a huge fan of the Vienna Philharmonic, but Karl Bohm's direction is SO slow that it robs the music of all sense of forward movement. The 6th, in particular, is almost coma-inducing. On balance, I prefer Claudio Abbado's under-appreciated cycle with the same orchestra, although Abbado's 6th is a bit slow for my taste as well.
