About the X250.8
The Pass Labs X250.8 is a high-end Class AB stereo power amplifier renowned for its refined design, building on nearly a decade of development. It operates in Class A for the first 25 watts into 8 ohms, transitioning to Class AB for higher demands, providing 250W/ch into 8 ohms and 500W/ch into 4 ohms. Featuring symmetrical circuitry, 56 output devices per channel, larger power supplies, and enhanced heat sinks compared to the .5 series, it delivers ruler-flat frequency response, ultra-low distortion, tight bass control via a high damping factor, and natural midrange and highs. The amplifier includes balanced XLR and single-ended RCA inputs, a bias current meter on the front panel, and is housed in a robust machined aluminum chassis. Praised for its three-dimensional soundstage, low noise floor, and ability to drive demanding speakers effortlessly, it pairs ideally with Pass Labs preamplifiers.
