Noske, I have the Brilliant Mozart and Bach sets and have been pretty pleased with them, I'm not very well versed in Classical music though, so am not a good judge of performance quality. I did read the Brilliant Beethoven set wasn't that good compared to the other two I do have.
Jasonbourne52, Is that 1967 Karajan a complete works set?
Jim, the Naxos set reviews I've read so far concur with your judgement. It's supposed to be a fairly complete set too with lots of odds and ends included.. Since the DG set is harder to find and pricier by far I'm leaning towards the Naxos or Warners.. Hopefully someone out there has the Warner set and can comment.
