Pass Labs X Series Power Amplifiers
The output stages of the larger Point 8 amplifiers bias more deeply into the Class-A operating region. These amplifiers glow with innovation. Their larger push-pull Class-A operating envelopes deliver low distortion and additional loudspeaker control at ordinary listening levels. And higher power MOSFETs, many more than usual, increase the amplifiers’ Class-A operation while running at fractions of their stated specs to enhance both performance and reliability.
Still not content, Pass Labs uniquely moulded each model’s front end to the specifics of its output stage so that the nine amplifiers’ front ends vary in size, voltage, bias current, dissipation, and single-ended vs. push-pull bias distribution. The directly coupled front ends, which house the input and voltage gain stages, maximise each model‘s output stage performance while imparting to each model its own subtle and unique sonic signature.
There’s more — including larger power supplies, more storage capacitance, more precise reference voltages, and new, larger heat sinks — but suffice it to say that with the Point 8 Series, Pass Labs move beyond cookie-cutter circuits.

X150.8 – Stereo Amplifier
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. But knowing the ear is not a microphone and the brain is not a tape recorder, Pass Labs designed this model to bridge the gap between measured performance and outstanding subjective musical experience. Simply put, the X150.8 will compel you to listen to your entire music collection again and again.
X260.8 – Mono Amplifier
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. Like all of the Class A/B .8's, this amplifier has some Class A bias, rewarding its listeners with a whole new zenith of sound quality.
X250.8 – Stereo Amplifier
This stereo Class A/B model represents a step up in power and performance from the X150.8 and, like all of Pass Labs products, has been painstakingly designed, tweaked, redesigned and fine-tuned to deliver maximum musical enjoyment. This hard work and creativity results in a greater “look-back” at the original musical performance, conveying additional insight to the artist’s creative intent. Isn't that what it's all about?
X360.8 – Stereo Amplifier
At 350 watts per channel Class A/B, the X350.8 is the largest and most powerful stereo power amplifier of Pass Labs line-up. Because Pass Labs care more about how holistic design affects the musical experience and relatively less about how parts affect specifications, you can expect superb and accurate representation of the recording performance and venue, as well as the distinctive layering of instruments captured faithfully.
X600.8 – Mono Amplifier
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. Exhaustive listening tests, not myopic focus on specifications have informed the development of this and the rest of the Pass Labs product offering, and you can hear it.
