The Pass Labs INT-25 is a pure Class A integrated amplifier delivering 25W/channel into 8Ω (50W into 4Ω) with exceptional transparency and musicality. It features a simplified single-ended preamp section from Pass Labs' higher-end INT models, paired with a direct-coupled XA25-derived amplifier section using industrial-grade power FETs. The design emphasizes minimal signal path components, no degeneration circuitry, and a constant-current bias system for low distortion (0.1% THD) and high damping factor (500). With three RCA inputs, remote control, and robust construction (49 lbs), it targets audiophiles seeking uncompromising sound quality with efficient speakers.
