Pass Labs
Pass Labs XA Series Power Amplifers
Designed for audiophiles by even more demanding audiophiles, they invite listeners into the music as never before. Pass Labs uniquely molded each model's front end to the specifics of its output stage so that the amplifiers front ends vary in size, voltage, bias current, dissipation, and singel-ended vs push-pull bias distribution. The directly coupled front ends, which house the input and voltage gains stages, maximise each model's output stage performance, while imparting to each models its own subtle and unique sonic signature.
These are Pass Laboratories ultimate expression of Power Amplifiers - the perfect blend of science and visceral emotion.

XA30.8 – Stereo Amplifier
An exceptional stereo power amplifier on many levels - high-biased MOSFETs providing higher-power Class-A operation, direct-coupled front-end circuitry for exceptionally high stability and larger, more robust heats sinks similar to those of the larger .8 amplifiers. The list goes on, but listening may tell you the XA30.8 represents a value high-point - quite possibly your particular optimal balance between performance and cost.
XA60.8 – Mono Amplifier
Offering all the sonic benefits of the .8 amplifier line, a pair of XA60.8's also grace the listener with mono-block performance: dedicated power supplies for each channel, dedicated circuitry for each channel and dedicated chassis' for each channel offer a cleaner, better defined image and soundstage. Beautiful to the ears and eyes, this model achieves levels of focus and intimacy normally associated with the finest tube amplifiers. The XA60.8's does all of this while providing greater control and power.
XA100.8 – Mono amplifier
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.
XA160.8 – Mono Amplifier
More of just about everything: 72 output power-MOSFETs, higher input impedance, higher capacity power supply and the ability to deliver over 320 watts per channel in Class-A with greater dampening. The 160.8's deliver power and finesse in spades. Voices take on shape and depth, piano notes arrive with full acoustic integrity and the rest of the rhythm section is delivered with both powerful attack and holographic sustain. The effortless conveyance of musicality and realism must be heard to be believed.
XA200.8 – Mono Amplifier
Are fabulous-sounding 400-watt-plus per channel Class-A peaks attainable without loss of the musical detail or audible meltdown? Yes, through repeated listening tests and continual technical innovation that push performance standards, the XA200.8 achieves what most amplifiers can only dream about. Even for the most demanding, complex musical passages in larger rooms at high sound pressure levels, this model offers headroom to spare.
