The new design uses double-shielded low noise toroidal transformers in external supply

The new design uses double-shielded low noise toroidal transformers in an external supply connected via aviation-grade circular connectors using silver over oxygen-free copper. The power supply is dual mono with two transformers with lower radiated and mechanical noise. Noise is the most prominent part of THD+N at low levels, so by lowering noise we get better resolution and dynamics.

The gain circuitry continues to use our favorite transistors from Toshiba but has a larger, higher biased, output stage like the Xs Preamp, and includes auto bias.

The larger output stage makes longer, and multiple cable runs easier to drive and gives us the advantage of simplifying our single-ended output circuitry while increasing performance.

The volume control is a single stage instead of two stages and has more range; it is quieter and more accurate. This is the same volume control as used in the XP-30.

Overall this makes for a quieter, more neutral, musical, and versatile control center for your system.

The XP-22 measures spectacularly well — but it really stands out sonically.

“Nelson Pass’ name is on the front door of Pass Labs and for good reason. He is very possibly the most important amplifier designer to walk the Earth. Here’s something that not every audiophile knows but is true, though: Nelson doesn’t design his namesake preamps. His colleague, Wayne Colburn, is the man behind all things preamplification at Pass Labs. And these Pass Labs preamps are just as lust-worthy as Nelson’s wonderful sounding, often hot-running, Class-A power amps.”
FutureAudiophile.com Review – 2024

“Pass Labs where calm Engineering 101 rules. Should inexplicables arise, they get sorted until everything works. Longevity from reliability is key. Expendables ship out to Hollywood elsewhere in the state. That’s apparent in no-nonsense cosmetics, beefy chassis, external power supplies to increase their footprint and categorical absence of iGen frills. In fact, the iGeneration won’t know what to do with a full tape loop…”

“More importantly, prior to the XP-22’s arrival neither of us had sampled any other dual-box Pass affair. This $9’975 model sits one step above its entry-level single-chassis XP-12 sibling, but the manufacturer’s preamp roster doesn’t end there.”
HiFi Knights Review – 2023

“The Pass Labs XP-22 preamplifier ($9,500 USD) and the XP-27 phono preamplifier ($11,500 USD) currently occupy the middle spots in the company’s line-up, just under the flagship XS models.”

“The new XP-22 from Pass Labs is a significant upgrade from the previous model. Based on new semiconductors and a new volume control, the two-chassis XP-22 vaults performance into another league.”
PartTimeAudio Summer Guide: Best preamps – 2022

“The two-box, solid state, line-level Pass XP-22 provides both balanced (XLR) and single-ended (RCA) inputs and outputs, plus a vestigial tape loop. The XP-22’s volume control—an Avago-sourced encoder that JCA describes as having “good bearings and a nice feel””
Stereophile Recommended Components – 2022

“The XP-22 preamplifier is a two-chassis design, the control module attaching to the identically sized power supply with a 9-pin JAE umbilical cable. The two boxes are stackable, and there are pieces of felt glued to the bottom of the preamp’s four feet to prevent scratching the top surface of the power supply.”
