Hmmmm, that was some time ago, or is my memory failing me? The ones with kt88's & a grille that looked like an army field transmitter? They were "powerhouses" of the time?
If so, I had heard a "re-capped" pair years ago driving dynamic speakers (no recollection of speakers, just the Lumleys -- a good sign), and I *do* remember a lush, expansive sound that was VERY enjoyable. I don't remember being stricken by detail & upper end extension and I THINK we were driving them with a DNM pre (which is quite detailed).
I suppose I haven't really answered yr question, well...
