As the entry-level iteration of Pass Labs' flagship Class A/B stereo power amplifier, the X150.8 boasts the same technical specs --150 watts per channel, 100K ohm input impedance-- and sonic attributes as its higher-end siblings. With the belief that the ear is not a microphone and the brain is not a tape recorder, X150.8 furnishes an immanent bridge between technical performance and a sublime musical experience. In other words, this amplifier will have you revisiting your entire music collection for many more repeat listens.
