The Pass Labs XA30.8 is a high-performance stereo power amplifier engineered to deliver 300 Watts into 8 Ohms per channel in pure Class A operation. Utilizing an oversized power supply, heavy-duty output topology, and a damping factor of 150, it drives real-world loudspeaker loads with surprising current headroom, precise low-frequency articulation, and exceptional transient speed. Offering 26 dB of gain along with high input impedances (50 kΩ single-ended RCA, 100 kΩ balanced XLR), it integrates easily into high-resolution source environments. Weighing 88 lbs with a continuous idle power draw of 370 Watts, the XA30.8 provides pure Class A liquidity, rich tonal texture, and dimensional spatial realism in a single-chassis stereo design.
