InPower Monoblock from Pathos Acoustics

Posted Mon May 14, 2007, 10:10 AM ET — By Larry Greenhill

The Pathos InPower monoblock amplifier ($13,500/pair) is a hybrid design offering 80W (at 0.4% THD, 5Hz–60kHz, ±3dB. It features some of the most beautiful industrial design I saw at the show. Designer Gianni Borinato describes it as a balanced, double INPOL power amplifier, with a zero-feedback, hand-matched. MOSFET output stage biased to run in class-A. The point-to-point wiring uses silver wire. Two triode tubes in the input stage are wired in opposite phase to form a double triode that is claimed to minimize distortion. The design proved its merit by driving the Focal 1037 Be loudspeakers with speed, dynamics, and excellent imaging. The room was a favorite among the Stereophile writers at the Show.

my biggest regret is that I didn't get to visit any of the rooms with the Focal speakers in them... I just didn't have time, and ironically enough, it is one of the speakers I really really wanted to hear. :(
