Chord Electronics ULTIMA Pre Pre-Amplifier

Description

Designed to be entirely uncompromising, the Chord Electronics ULTIMA Pre Pre-Amplifier is a world-class amplifier with advanced proprietary Chord Electronics technology. A product of three decades of research, design and engineering here in the UK, it benefits from true dual-mono construction with separate ultra-high-frequency power supplies for each channel, giving the best possible separation. With the addition of valuable low-noise circuitry, the noise floor performance is exceptional, at beyond -117dB.

Featuring impressive double-height dimensions, the Chord Electronics’ ULTIMA preamp has been created to perfectly complement the flagship Chord Electronics’ ULTIMA mono power amplifier, also the most advanced in the company’s 30-year history. With wide-ranging inputs and outputs, including balanced connectivity, the Chord Electronics’ ULTIMA offers complete flexibility for high-performance partnering equipment, enhanced further by the fascia-mounted separate frequency EQ adjust controls for the left and right channels. Headphone outputs offer further flexibility for late-night and personal listening in style.

Each Chord Electronics’ ULTIMA preamp is hand-made in Chord’s Kent factory, with the various stages of build and production carefully overseen by one highly skilled technician. Sensitive internal circuit features are protected by solid milled aluminium shielding to prevent RF interference and Chord Electronics’ legendary UK-produced aircraft-grade aluminium provides a solid and resonance-eliminating enclosure for the electronics within, complemented by the famous Integra Leg System.

The Chord Electronics’ ULTIMA is the ultimate expression of the finest high-performance, ultra-fast, ultra-high-power amplifier technology available today.
