Product Description

The ULTIMA monoblock power amplifiers deliver unsurpassed power delivery and are capable of effortlessly driving any speaker. ULTIMA is the company’s most accomplished amplifier in its 30-year history and one that draws on Chord Electronics’ three decades of proprietary-technology amplifier manufacturing. It features an all-new circuit topology, the first completely new design since those early days. The new dual-feed forward error-correction amplifier technology is a progression of Dr. Malcolm J Hawksford’s (emeritus professor at Essex University) technical paper, refined by Bob Cordell of Bell Labs.

ULTIMA contains Chord Electronics’ next-generation amplifier tech, a design that features Cordell’s advanced dual-feedforward error-correction topology, plus John Franks’ own advanced concepts in ultra-high-frequency power supplies.

The ULTIMA mono amplifier unit has an incredible 64 proprietary MOSFET power devices that demand the most advanced and refined drive circuitry, suitably devoid of sound-degrading components. The drive circuitry features an ultra-low-distortion, high-voltage amplifier operating at very high speed: 300 volts-per-microsecond technologies with advanced feed-forward and feedback compensation techniques.

ULTIMA is incredibly powerful and offers 780 watts into 8 ohms, 1,400 watts into 4 ohms, and 2,500 watts into 2 ohms. ULTIMA’s peak output current exceeds 500 amps, an extremely high current differentiated by the speed at which the dynamic peaks can be delivered, bringing astonishing dynamics, fidelity, and unrivaled musicality.

ULTIMA is truly an unprecedented amplifier design with exceptional performance and is one of the most advanced hi-fi amplifiers in the world.

Hi-Fi Pig
ULTIMA amplifiers benefit from a redesigned fascia featuring John Franks’ latest aesthetic. The precision CNC-machined fascia is made from aircraft-grade aluminium and features a solid 28-mm thick front panel, enhanced by a recessed spherical polycarbonate power button that illuminates for standby and operation modes; a discreet, hidden front panel switch, located in the vertical split line, enables dimmable lighting…
