I am listening to a Bedini 25/25 Phase two right now. That's right, a 25 watt/channel true class A amp that sings. It did likewise with my Acoustat 2+2s as well. This amp was designed to drive a pair of Quads per channel. Very high current little amp. Any of the 800 Series amps will do well with these speakers. For class A/B solid state, the Perreaux PMF5550/5570/5150 amps will do the job(on any speaker). The PMF3400 is another good match. Good luck finding any of these amps. I suspect the McCormack amps will also work. The Mani 2s are incredible for their size. Have Fun...
