Xs Series Preamps
Ultra High-End Preamp & Phono
When we began development of the Xs power amplifier five years ago, we knew that we would also need a companion piece.
We were given “carte blanche” on the design and an unlimited budget, the result of this is the Xs Preamp.
True “dual-mono” design
only component shared between channels other than casework, being the AC power connection to house power
includes its own regulated power supply
Negligible channel to channel “cross-talk”
Xs Preamp Dual Chassis Preamp – $38,000
This large, dual-chassis preamplifier is built in true dual-mono arrangement. Each channel has its own power supply board with over 100,000uf of capacitance for unfettered transient response. Noise levels have been dropped from the already low-noise XP30. Refined circuit design and layout, new gain-stages with auto-bias and DC compensation all combine for optimal performance. But it all comes down to sound; once you listen to the Xs preamplifier, there is no going back.

The Absolute Sound
“For me, the Xs series has drawn a line in the sand and has redefined the ‘state of the art’.”
“Have a sound that is almost beyond description in words.”

Xs Phono Dual Chassis Phono – $45,000
The Xs Phono preamplifier represents an all-out assault on the state-of-art in Vinyl and the most intensive and difficult design effort made at Pass Laboratories. The final product of this massive effort extracts the utmost performance from a simple topology and operates with the extremely small and delicate signals coming from today’s wide variety of phono cartridges. The result is music that emerges from a quieter background and blooms into a richer, more precise soundstage.
XP Series Preamplifiers
The Pass Laboratories XP-10, XP-20 and XP-30 preamplifiers are the natural descendants to the long lived, highly acclaimed and successful X series of Pass Laboratories line-stages.
The XP preamplifiers sound more dynamic, bass lines are more clearly, cleanly and accurately delineated
Clear bass lines
cleanly and accurately delineated
Fine nuances and detail
instruments and voice are presented in a greatly refined spatial envelope and with better spectral balance.
XP-32 – $18,375
The XP-32 is a three-piece modular preamplifier consisting of one control/power supply chassis and two additional gain chassis each containing analog signals of a single channel. 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.
XP-27 – $12,075
HPA-1 Headphone Amplifier – $3,675
Announcing the new Headphone Amp from Pass Labs!
Like the XP preamplifiers, the HPA-1 is the result of great attention to detail.
Starting at the power cord, the AC line is first filtered for high frequency noise and then isolated by a special toroidal transformer shielded by mu-metal for lower magnetic noise and shielded for electrostatic noise by a separate Faraday shield, grounded to analog ground. This is followed by fast/soft recovery rectifiers, generous CRC passive filtering and sophisticated discreet DC regulators and then more passive RC filters.
Works with headphones
with impedances of 15 ohms to 600 ohms
Low feedback wide bandwidth discreet design.
direct coupled Mosfet output stage
Custom low noise Torodial power transformer
with a Farady shield
Discreet regulated power supply for audio circuits.
Awards and Reviews
“To put it bluntly, Pass Labs HPA-1 is an exceptional, very addictive headamp/preamp combo every aficionado should at least audition once an opportunity strikes.”
” If I did not know that the HPA-1 was transistor-based, I would’ve been fooled: the HPA-1 had the natural warmth and slight fullness that mimic tubes.” ” In my view, headphone listening is about intimacy, and the HPA-1 is nearly perfect in this regard.”
“As far as headphones go, the HPA-1 is a brilliant amp which deserves every bit of praise I’ve thus far heaped on it.”
Headphone Amplifier of the Year – 2016
The Absolute Sound
Best Headphone Amplifier – Best of Awards – 2016
“One Of The Best HPAs In The Audiophile World!”
“The HPA-1 had an effortless quality that made recorded music sound more like the real thing.”
“Pass Labs, one of the most prestigious names in audio, has launched a terrific headphone amplifier”
“in bass clarity and authority and in midrange transparency, the Pass Labs HPA-1 is without peer”
“The Pass HPA-1 is on the top tier of the world’s finest headphone amplifiers”
“This thing sounds so damn good twenty minutes out of the box”
“An amplifier that drives headphones to exceptional performance”
“The best I’ve heard from a headphone amp anywhere near the HPA-1’s price.”
“the Pass Labs HPA-1 is a bona fide muscle amp in the guise of an equal-opportunity preamp with headfi function.”
“Dynamics and authority are two of the best qualities in all listening sessions with the HPA-1, regardless of the headphone. With a great current delivery it also drives any planarmagnetic headphone, with an absolute control.”
These are Pass Laboratories ultimate expression of Power Amplifiers the perfect blend of science and visceral emotion.
If there’s a more emotionally satisfying amplifier anywhere, we’re not aware of it.
The successor to our already lavishly praised and well regarded Supersymmetry patent. Every technical effort has been made to assure exceptional specifications, among these:
for lower electromagnetic noise
with greatly enhanced storage capacitance
Banks of redundantly parallel high speed
and soft recovery rectifiers
with improved high frequency
Larger and quieter transformers
Improved passive decoupling
Lower power standby
of 200 k-ohm balanced with negligible capacitance
