The Pass Labs Xs 300 is a flagship two-chassis monoblock power amplifier engineered to deliver 300 Watts into 8 Ohms in pure Class A operation. Utilizing a dual-chassis architecture that completely isolates the massive power supply from the sensitive gain stages, it provides uncompromised current delivery, absolute signal purity, and exceptional thermal management. Featuring 26 dB of gain alongside balanced XLR and single-ended RCA inputs, the Xs 300 drives complex loudspeaker loads with authoritative low-frequency control, wide dynamic scale, and micro-detail resolution. Weighing over 300 lbs per channel and consuming 900 Watts continuously, it serves as an endgame amplification reference for ultra-high-end two-channel systems.
