You're best off choosing the most transparent amp you can afford -- otherwise you're not benefiting from that plasma tweeter.
In my listening room, 48 Watts SET is enough to drive my Lansche speaker ( oficial eff 99db/w, but I guess 95db/w)
Interesting. The Lansche I heard (a 3-way with 3 front firing drivers) began to sing only after we connected +60W class A (SS) to it. If you're getting away with a 45W tube, I'd say stick with it!
Otherwise, you need to search for amps that give you both power and transparency, i.e a major investment in money & time; at this level, we can offer only "possibilities" IMO.
To return to your original choices, I haven't heard the big Berning; the big Jadis, however, are not it (outstanding though they may be). Regards
