They don't have the richness of other earlier mullards or the tung sol black glass, and don't have the extension of the telefunkens either. There are a lot of choices in 12au7s. The late Mullards are better than current stuff but really can be bettered even in that price range regardless of tastes...
For reasonably priced tubes instead of the reference ones I just mentioned, check out Westinghouse and valvo, or run your tastes by one of the small tube gurus from audiogon for some rarer selections (I can recommend several I trust if you like).
Good luck!
