Chord Electronics Ultima 6

Chord Electronics
180W Stereo Power Amplifier

The Chord ULTIMA series of stereo power amplifiers has achieved legendary status, both in and outside the recording studio, thanks to innovative clean-power technologies and custom components. These amplifiers have the remarkable capability to instantly respond and provide substantial power, all while preserving transparency and minimizing distortion to an extraordinary degree. The result is nothing short of a masterpiece.

The ULTIMA 6 currently provides the most cost-effective entry point into our next-generation ULTIMA family of stereo power amplifiers. It builds upon the success of its award-winning predecessor, the SPM 1050 MK II, by incorporating our groundbreaking next-generation ULTIMA amplifier technology.

This new 180-watt model, featuring John Franks' innovative dual-feed-forward circuitry, delivers lightning-fast response and effortless power, resulting in astonishing dynamics and timing that set new standards for fidelity.

The development of our dual-feed-forward topology, which took 30 years to perfect, represents a significant breakthrough and marks the first entirely new circuit design from us in three decades. ULTIMA amplifiers have been meticulously engineered to meet the demands of the most exquisite hi-fi systems, representing the pinnacle of high-performance, ultra-fast, high-power amplifier technology available today.

The ULTIMA 6 boasts an impressive array of 16 proprietary MOSFET power devices, which necessitate the most advanced and refined drive circuitry. It features an ultra-low-distortion, high-voltage amplifier that operates at an astonishingly high speed of 300 volts per microsecond. Our TO3-style dual-die lateral-matched MOSFETs are under continuous monitoring with error-correction circuitry in the output stage. The amplifier also includes fully balanced input circuitry with DC-tracking servos and comprehensive temperature compensation.

While sharing the same genetic makeup as our flagship and reference-level monoblock amplifiers, the ULTIMA 6 offers greater practicality and affordability due to its distinct power output.

The amplifier is housed in our renowned aircraft-grade solid aluminum casing, providing a high-end and resonance-free enclosure for the electronics. The front panel has been redesigned with a 28-mm-thick fascia that reflects John Franks' latest aesthetic. An illuminated spherical polycarbonate power button discreetly indicates standby and operational modes, and a concealed front panel switch, located within the vertical split line, allows for adjustable lighting.

On the rear panel, you'll find both balanced and unbalanced connections, high-quality loudspeaker terminals, a 12 V trigger, and a C-19-type IEC connector.
