Silly me. I was thinking of replacing my beloved but nearly 30 year old pair of KEF Reference 104/2s with a pair of TSM MMi, to be driven by my Proceed Amp 3 or HPA-3. The last time I balanced tubes was when I was a grad student working in a psychoacoustics lab that had a dozen or so MC-60s. What a PITA that was. Guess I'll stick with the 104/2s tell one of them dies.
