I run a pair of Totem Mani-2's (4ohm/85db) and had previously auditioned them with several tube amps. The closest to what you're thinking would have been a Jolida 502B (60W rated/85W max) There were a couple of others, a Prima Luna Dialogue 2 and a Synthesis (Italian but sorry, can't remember the model) both of which were of lower power. Although each of these amps did drive the Totems nicely in some areas, my overall opinions kept me looking for another tube amp without the deficiencies I was hearing. The sound was always, well, too thin if that makes sense. In the interim I pushed them quite satisfactorily with a W4S STI500. Then I found my Cary CAD-120S MkII (120W Ultra/60 W Triode) with which I have been thrilled. My search has ended for now. Having inefficient, power hungry speakers made for a long, sometimes frustrating search, auditioning amps that many (especially sellers) told me would pair well with the Mani-2's. I ended up where I always suspected I needed to be...with a tube amp of higher output. FYI- I listen to broad range of musical styles, 85% vinyl/15% CD. YMMV. Good luck.
Amp and speaker matching.
I wanted to know if anyone out there has driven a harder load speaker (86db to be exact), with a Tube Amp around 70 watts? I was thinking of driving a pair of Dynaudio Contour 3.0's with a pair of Prima Luna 7 monoblocks 70watts. Currently I use a Solid State amp 350Watts. The Dyns love power so im afraid to drop down in power.
