The Pass Labs XS Phono is a flagship two-chassis phono preamplifier engineered to extract maximum resolution and emotional nuance from Moving Magnet and Moving Coil phono cartridges. Utilizing a dual-chassis layout that physically isolates the sensitive analog equalizers from the power supply, it achieves an extraordinarily low noise floor and RIAA accuracy within ±0.1 dB across the 20 Hz to 20 kHz spectrum. Featuring three independent input channels and selectable gain settings of 56 dB, 66 dB, and 76 dB, it offers precise cartridge matching for ultra-low-output designs. Weighing 80 lbs across both chassis with a continuous power consumption of 55 Watts, the XS Phono sets a benchmark for analog transparency, dynamic scale, and spatial realism.
