'Long experience of Beethoven makes me prefer the music to sound more raw and revolutionary. This doesn't sound like music to storm the barricades'.
I very much agree with this - it's this feeling that makes me always shy away from 100% endorsement of Karajan's Beethoven. I remember reading a review somewhere in which it was remarked that Karajan's Beethoven sounds as if the outcome of the revolution is a foregone conclusion, or words to that effect. I am paraphrasing from memory there but it was along those lines. I also think that many conductors, not only Karajan, don't get the sense of revolutionary fervour into the Ninth, particularly. The adagio is treated as a bastion of beauty and calm but I always want it to have more force to it - that's why I don't find a problem with the HIP performances that come in a lot quicker than how Karajan/Bernstein etc played it. As a general rule, I find live recordings of the Ninth more compelling as they seem to have rather more vim.
