The middle sibling of the XA.8 series, the XA100.8’s realize a muscular yet highly refined sonic profile. Like all Pass Laboratory’s power amplifiers, they features both single-ended and balanced inputs, Furutech five-way binding posts and a convenient ground terminal for safe subwoofer connection. Improved constant-current sourcing, precise voltage references and current-feedback all represent new benchmarks in state-of-art amplifier design. The result is a larger, more realistic soundstage, sharper transient response and the prized ability to reach concert-hall dynamics and realism without strain.
