Hafler P-225
Little is documented about the Hafler P-225, a professional power amplifier from the David Hafler Company in the early 1980s. The fullest period account is Modern Recording (January 1984, p.54). It calls the amp conservatively rated at 175 watts per channel into 4 ohms, with less than 0.03% THD from 20 Hz to 20 kHz. The review also details a push-pull complementary symmetry circuit with MOSFET output devices and quality components throughout. That topology is said to avoid the complex, sonically degrading current-limiting circuitry common in other designs. Inputs are 1/4-inch phone jacks. Outputs are heavy-duty five-way binding posts on standard 3/4-inch centers.
Recording Engineer (December 1983, p.148) adds that the amp could be bridged to mono with an internal switch, delivering 350 watts in mono mode. The load isn't stated in the surviving text. Beyond those professional-audio trade mentions, the record is thin. No original price or deeper review coverage has surfaced in the Archive's sources.
