Spiker:
I thought when I worked through more of the Decware site I would understand your advice, but now I'm more confused.
Am I correct in understanding that to work with the SET tube amps I'd have to get a speaker set with a sensitivity over 90db? (Rules out the Totems.) I am attracted by the clarity and 3d imaging attributed to the tube amps (& find tubes quite beautiful too) but am baffled by almost everything on the Decware site. Obviously this is because I am ignorant of the whole (somewhat hermetic) field. If you (or anyone) can point me in a direction to get educated, I'll be grateful.
