Irvrobinson, no, i never tried the SF with higher power amps. Maybe i should now for curiosity, since due to planning the roll-over to a tube amp, not long ago i got a aprox 100w onkyo receiver for home cinema (with some mordaunt-short speakers) so i have separate systems now for music /movies. I watch cinema a lot and wasn't imagining tiring those delicate 300B with movies...
Amp's nominal power rating - any use?
I just paired a couple of Coincident Frankentein monos with my SF Guarneri Homage. The sound is great (fat, rich, dynamic, transparent) and sounds well with any type of music (opera, rock, electronic...). These are 8W monoblocks and sound like with more power or at least the same as my previous fabulous pass aleph 3 (30W class A SS). Of course it depends if tubes not tubes, class A or not, speaker sensitivity, impedance load, room dimensions etc, but what i see is that it's not a relevant criteria at all on its own. Maybe there should be some transformation formula to take into account some of these factors to get some Apparent or Perceived Power, but maybe it would be hard to take into account all factors. Any ideas, opinions, on this?
