Pass Labs build FET amplifiers with excessive output stages, huge heat sinks and massive power supplies. They use the highest quality components in simple linear topologies, assembled and tested with care and subtlety. They measure well, sound great, and are reliable.
Advanced technologies and real-world testing combine to create the INT-60 which presents 60 glorious watts per channel into 8 ohms, and doesn't leave class A until 30 watts thanks to its high-bias operation. Delivering higher quality musical fidelity for your enjoyment.
The INT-250 utilises the synergies developed in the .8 series power amplifiers. 250 watts per channel of listening pleasure. The INT-250 drives large, demanding and relatively inefficient loudspeakers at higher volumes without batting an eyelash, singing beautifully.
The XP-12 uses an efficient toroidal design power supply with both an electrostatic and Mu metal shield along with vacuum impregnating and epoxy fill. Single stage volume control borrowed from the XS line preamp. Gain circuitry with Toshiba transistors.
Toroidal transformers in an external supply connected via aviation-grade connectors using silver over oxygen-free copper. Gain circuitry with Toshiba transistors. Single stage volume control. A quieter, more neutral, musical, and versatile control centre for your system.
Three-piece modular preamplifier. The XP-32 generates less noise, crosstalk and distortion while delivering greater dynamic range, gain, output voltage and output current. But it is the sound, not the technical excellence, that truly makes this a breakthrough instrument.
As the entry-level class A/B stereo power .8 amplifier, the X150.8 features many of the same technical and sonic attributes of its larger brethren. It features 150 watts per channel, 100K ohm input impedance and operates “higher” into Class A than its predecessors.
This stereo class A/B model represents a step up in power and performance from the X150.8 and, like all of our products, has been painstakingly designed, tweaked, redesigned and fine-tuned to deliver maximum musical enjoyment.
The X350.8 is the largest and most powerful stereo power amplifier of Pass Labs line-up. You can expect superb and accurate representation of the recording performance and venue, as well as the distinctive layering of instruments captured faithfully.
The X260.8 is a refined musical instrument delivering 260 watts into 8 ohms, and combines power and finesse with all the benefits of mono-block performance. Its measured performance - distortion, bandwidth, noise, and resolution is beyond reproach.
The X600.8 monoblock amplifiers deliver 600 watts into 8 ohms. Even more impressive they effortlessly drive the most demanding loudspeakers to musical nirvana, be the performance full scale orchestra, high-decibel rock band or string quartet.
Great sound at slightly lower power, without frills, at a lower price. It embodies new components and innovative circuits coupled with the best elements of the previous generation. Faster, lower distortion, lower noise, higher damping and larger Class A operating envelope.
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 heat sinks similar to those of the larger .8 amplifiers.
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.
The middle sibling of the XA.8 series, the XA100.8's realise a muscular yet highly refined sonic profile. A larger, more realistic soundstage, sharper transient response and the prized ability to reach concert-hall dynamics and realism without strain.
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.
Through repeated listening tests and continual technical innovation, 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.
The XP17 has an all-new input circuit that is symmetrical and lower in noise and distortion with greater drive capability. Noise is the most prominent part of THD+N in the first section of a phono stage. By lowering noise we get better resolution and dynamics.
The twin chassis XP-27 eclipses the already exceptional performance of the well-reviewed and well-received XP-15, XP-25 & XP-17, delivering enhanced RIAA performance at a fraction of the previous distortion. Input and gain circuitry are similar to that found in the Xs Phono.
The HPA-1 is one of the very best sounding headphone amplifiers available today. With low feedback, wide bandwidth and a direct coupled MOSFET output stage, this musical instrument drives even the most difficult headphone loads with ease, power and grace.
