The Pass Labs XP-27 is a world-class, dual-chassis phono preamplifier designed to extract every microscopic nuance from high-end vinyl playback systems. By physically separating the sensitive gain circuitry from the power supply, it achieves a vanishingly low noise floor and extraordinary dynamic range. It represents a significant evolution in analog engineering, offering the transparency and musicality required for the world’s finest cartridges.
Key Features
-
Dual-Chassis Architecture: Complete physical isolation between the power supply and gain stages eliminates electromagnetic interference for a dead-silent background.
-
Independent Dual Inputs: Features two sets of inputs with independent memory for gain and loading, ideal for systems with multiple tonearms or turntables.
-
On-the-Fly Adjustments: Front-panel controls allow for real-time adjustments of resistive and capacitive loading while the record is playing.
-
Ultra-Low Noise Circuitry: Employs new, high-efficiency shielding and a low-noise input stage derived from the flagship Xs Phono.
-
Pure Class A Output: High-bias discrete circuitry ensures a rich, holographic soundstage with the natural warmth of the original recording.
The Architecture of Absolute Silence
The XP-27 utilizes a two-chassis design to tackle the primary challenge of phono amplification: noise. Because phono signals are incredibly small, they are highly susceptible to the electrical hum and vibration inherent in power transformers. By housing the power supply in a separate dedicated enclosure connected via an umbilical cable, Pass Labs ensures that the amplification stage remains unpolluted, allowing the subtlest micro-dynamics to emerge with startling clarity.
Dual-Chassis Isolation
Separate power supply ensures the lowest possible noise floor for delicate phono signals.
Front-Panel Control
Easily adjust resistive and capacitive loading in real-time for the perfect cartridge match.
Dual Input Support
Connect and store independent settings for two turntables or tonearm configurations.
Unmatched Versatility and Control
Unlike many phono stages that require cumbersome internal "dip switches," the XP-27 puts control at your fingertips. The front panel features intuitive knobs for resistive loading, capacitive loading, and gain selection. This allows the listener to fine-tune the interface between the cartridge and the preamplifier in real-time. Whether you are using a delicate low-output moving coil or a high-output moving magnet, the XP-27 can be perfectly optimized to capture its unique character.
Reference Grade Musicality
Beyond its technical prowess, the XP-27 is a triumph of musical voicing. It delivers a massive, three-dimensional soundstage with precise instrumental placement and tangible weight. The RIAA equalization is executed with extreme precision using high-quality components, ensuring that the tonal balance remains natural and life-like. It avoids the dry, clinical sound of many solid-state designs, offering a liquid presentation that makes long listening sessions deeply involving.
Other Key Features
- Dual-Chassis Power Isolation: Separates noisy AC components from sensitive audio signals.
- Dual Independent Inputs: Each input remembers its specific loading and gain settings.
- Front-Panel Loading Controls: Allows resistive (30Ω to 47kΩ) and capacitive (100pF to 750pF) adjustments.
- High-Current Class A Output: Easily drives long cable runs to your main preamplifier without signal loss.
- Switchable Gain Levels: Three-stage adjustment (53dB, 66dB, 76dB) to suit any cartridge output.
FAQs
How is the XP-27 different from the XP-17?
The XP-27 uses a two-chassis design for superior isolation and provides dual inputs with convenient front-panel controls, whereas the XP-17 is a single-chassis unit.
Can I use two different turntables at once?
Yes, the XP-27 has two independent inputs, allowing you to switch between two turntables or tonearms without swapping cables.
Is it compatible with both MM and MC cartridges?
Absolutely. With gain settings up to 76dB and a wide range of loading options, it can perfectly match any cartridge on the market.
Does it have balanced outputs?
Yes, it features both balanced XLR and single-ended RCA outputs for integration into any high-end system.
Why adjust loading while the music is playing?
Adjusting loading on-the-fly allows you to hear the immediate impact on high-frequency extension and soundstage, helping you find the "sweet spot" by ear.
