Hi Md30 - I have yet to change the stock 12AX7's. I have, however, changed the stock 12AU7's, (one of them died on me), and I actually regret going with a similarly priced brand. The stock ones were a little better, and the next time I need some, I will go back to them, unless I decide to try something else entirely. Supposedly the 12AU7's make the least difference in the overall sound, but it was noticeable nevertheless.
As far as power tubes go, right now I am using some EL34's in my Dialogue 2, Electro-Harmonix. And yes, the highs may be a bit harsh until the tubes have been in use about 50 hours or so, depending on the tube, really. I have obviously not done a whole lot of tube rolling, so any experiences you have to share would be appreciated.
