Audio Research Reference 10 Preamplifier

There are moments in high-end audio that define the absolute state of the art. The Audio Research Reference 10 is such a moment. This is not merely a preamplifier; it is a definitive statement, a magnificent two-chassis instrument engineered to be a completely transparent window to the original performance. By completely separating the massive, tube-regulated power supply from the all-tube audio circuit, the REF 10 achieves a level of purity, silence, and dynamic freedom that is simply unattainable in a single-box design. Controlled by a stunning touchscreen interface and featuring a breathtakingly large vacuum-tube signal path, the Reference 10 is the ultimate control center for the listener who seeks not just to hear the music, but to be completely immersed within it.

Key Features

• Two-Chassis Reference Design: A separate, full-size chassis for the power supply completely isolates the audio circuit from all electrical and mechanical noise, creating an unprecedentedly black background.
• Touchscreen Command Center: A beautiful 7-inch front-panel touchscreen provides intuitive, complete control over all functions, including input selection, volume, balance, and system information.
• Massive All-Tube Signal Path: The audio circuit features a staggering ten 6H30 vacuum tubes (five per channel) in a pure Class-A, fully balanced, zero-feedback configuration.
• Tube-Regulated Power Supply: The separate power supply chassis features its own 6550WE and 6H30 tubes for vacuum-tube regulation, ensuring the purest possible power for the audio stage.
• True Dual-Mono Audio Circuit: The audio chassis features a true dual-mono design, including dual power transformers, for the ultimate in channel separation and stereo imaging.
• Comprehensive Connectivity: A vast array of inputs, including six balanced (XLR) and two single-ended (RCA), plus a processor pass-through for home theater integration.
• Flexible Outputs: Features two main outputs and a record out, each provided in both balanced (XLR) and single-ended (RCA) formats.
• Built-in Tube Hour Meter: An integrated timer on the touchscreen display tracks the usage of the vacuum tubes.
• The Pinnacle of ARC Build Quality: Two matching, full-size chassis, handcrafted in Minnesota, USA, represent the ultimate expression of Audio Research design and construction.

The Purity of Separation

The Reference 10’s two-chassis design is the ultimate expression of high-fidelity principles. By placing the massive power transformers and complex, tube-regulated circuits in an entirely separate, full-size chassis, any potential for electrical or mechanical interference with the delicate audio signal is eliminated. This complete isolation creates a profoundly silent background, allowing the audio circuit to amplify the signal with a level of purity and clarity that reveals the finest, most subtle details in a recording. The result is a soundstage of breathtaking scale and focus, where music emerges from a void of pure blackness.

The Touch of Command

Interacting with the Reference 10 is as luxurious as listening to it. All setup and operational controls are accessed via a beautiful and intuitive 7-inch touchscreen on the front of the power supply unit. From this command center, you can effortlessly select from the eight inputs, precisely adjust volume and balance, customize input names, and monitor tube hours. This elegant, modern interface removes all guesswork and provides immediate, comprehensive control over the most advanced line-stage preamplifier in the world.

An Ocean of Tubes

The audio chassis of the REF 10 is a testament to Audio Research's absolute mastery of vacuum tube design. The massive, fully balanced, pure Class-A circuit employs ten 6H30 dual-triode tubes—five per channel—to handle the signal. This no-compromise, dual-mono approach ensures a sound that is dynamically explosive, harmonically complete, and dimensionally holographic. The dedication to tube purity extends even to the power supply, which uses its own 6550WE and 6H30 tubes for regulation, ensuring that the audio circuit is fed the cleanest, most stable power imaginable.

A Statement in Craftsmanship

The Reference 10 is the pinnacle of Audio Research's five-decade legacy of craftsmanship. Each of the two massive chassis is meticulously assembled by hand in Minnesota, USA, undergoing the most rigorous testing and quality control. The flawless finish of the classic brushed aluminum faceplates and the robust, anti-resonant construction are a testament to its "built-for-a-lifetime" philosophy. This is not simply a component; it is an heirloom-quality instrument designed to be the unchanging, authoritative heart of a world-class audio system for generations to come.
