The Campaniles may need more power than the 50 watt Audio Aero amps could provide (depending on the room size), but I would still trade off some of the bass slam and dynamics for the musicality of fine tubes!
Amp Choice for Acapella Campaniles
I purchased a set of Campaniles last summer and have been trying to optimize them since then both with respect to room placement and amps. The speakers utilize a plasma tweeter, a midrange (non-compression) horn using a Dynaudio driver and four 10" SEAS drivers for woofers in individual rather large sealed boxes (2 woofers per 30" by 12" by 28" box). I have to date tried two very different amps (Parasound JC-1's and Wolcott 220 mono tubes). The JC-1's are still breaking in but thus far are promising, still lacking the dimensionality and warmth of the tubes but with superior control of the bass and dynamics. I understand from the designer that the JC-1's will gain in both of these areas as they break in. Any suggestions with respect to other possibilities with these very revealing speakers. By the way, the JC-1's exhibit absolutely no brightness or zip in the top end. I think that 100 watts would be the minimum amp size needed.
