The Pass Labs Xs Phono is a reference-grade, dual-chassis phono preamplifier designed for the most demanding vinyl enthusiasts. It represents a "no-compromise" approach to analog playback, featuring a massive external power supply and three independent inputs to accommodate multiple tonearm setups. By isolating delicate phono signals from the power source, it achieves a vanishingly low noise floor and extraordinary dynamic range.
Key Features
- Dual-Chassis Isolation: Separates the high-current power supply from the ultra-sensitive phono circuitry to eliminate noise and hum.
- Three Independent Inputs: Allows for the simultaneous connection of three different turntables or tonearms, each with its own saved settings.
- Pure Class A Design: Hand-matched components and a high-bias circuit deliver the warmth, texture, and detail that vinyl collectors crave.
- On-the-Fly Adjustments: Features a front-panel interface for real-time control over loading, gain, and filter settings without opening the unit.
- Massive Power Reserves: The dedicated power chassis provides rock-solid voltage regulation, ensuring consistent performance across all frequencies.
Engineering the Ultimate Analog Path
The Xs Phono is the result of years of research into the behavior of low-level signals. Because phono cartridges produce such small voltages, they are highly susceptible to interference; Pass Labs addresses this by housing the transformers and rectifiers in a completely separate 50-pound chassis. This ensures that the amplification stage remains silent, allowing the listener to hear deep into the grooves of the record to reveal layers of music previously hidden by noise.
Dual-Chassis Power
External power supply isolation for the lowest possible noise floor.
Three Independent Inputs
Connect and store custom settings for three separate tonearms.
Real-Time Adjustments
Fine-tune gain and loading on-the-fly for the perfect cartridge match.
Versatility for the Collector
Modern high-end analog systems often feature multiple tonearms with varying cartridge types (MM/MC), and the Xs Phono is built to manage them all. Each of its three inputs can be independently configured for gain (56dB to 76dB) and loading (resistive and capacitive). These settings are stored in memory, so you can switch between a mono cartridge and a stereo moving coil at the touch of a button, ensuring each cartridge performs at its absolute peak.
Musical Truth and Texture
Beyond the technical sophistication, the Xs Phono is celebrated for its ability to convey the "soul" of a recording. It provides a massive, holographic soundstage where instruments have a physical presence and weight. The RIAA equalization is executed with extreme precision, ensuring that the tonal balance remains natural and life-like. Whether playing a vintage jazz pressing or a modern audiophile reissue, the Xs Phono delivers a level of emotional engagement that is unsurpassed in the analog world.

FAQs
Can the Xs Phono handle low-output Moving Coil (MC) cartridges?
Yes, with up to 76dB of gain, it can effortlessly drive even the most demanding low-output MC cartridges with total transparency.
Does it support Moving Magnet (MM) cartridges?
Absolutely. The gain and loading are fully adjustable to accommodate the specific requirements of MM and high-output MC cartridges.
What is the benefit of the front-panel controls?
Unlike many phono stages that use internal "dip switches," the Xs Phono allows you to adjust loading and gain while the music is playing to find the perfect setting by ear.
Is the Xs Phono a tube or solid-state design?
It is a pure Class A solid-state design, offering the warmth and liquidity of tubes with the reliability, lower noise, and precision of high-end transistors.
How does it connect to the preamplifier?
It features both Balanced (XLR) and Single-Ended (RCA) outputs for easy integration into any high-end audio system.
