About the Power 2
The Sonic Frontiers Power 2 is a stereo tube power amplifier produced circa 1997-1999, delivering 110 watts per channel into 8, 4, or 2 ohm loads via a push-pull output stage using eight 6550 or KT88 output tubes. Its fully balanced circuit topology uses an input cathode follower with 6922 tubes, two cascaded differential plate-loaded 6922 voltage-amplifier stages, and a driver cathode follower using 5687WB tubes directly coupled to the output tube grids. The design is fully balanced throughout including the output transformer, accepting both balanced XLR and single-ended RCA inputs with balanced global feedback. Rated frequency response is 5 Hz to 40 kHz at 1 W, power bandwidth to 90 kHz at 110 W, THD under 1% at full power, and damping factor greater than 50. The chassis weighs about 110 lb (50 kg). Widely regarded for its robust build quality and a sonic character that is sunny and warm yet highly detailed, with excellent dynamics and a realistic soundstage.
