PASS Labs XS300 Monoblock Power Amplifier (Pair)

The XS series represents Pass Laboratories' reference-grade monoblock amplifiers, engineered for uncompromising music reproduction. The XS 300 delivers 300 watts of Class A power per channel, utilizing dual-chassis design with separate power supply and amplifier sections to minimize noise and maximize clarity. A higher-power constant-current source combined with single-ended bias circuitry reduces distortion while providing precise harmonic control. Every aspect has been refined through rigorous listening evaluation to achieve exceptional musical performance and transparency across all frequencies.
