The ULTIMA mono amplifier is designed for the most advanced high-end audio systems, capable of driving speakers with high demands. It offers unparalleled power delivery and can drive any speaker without any difficulty.

The ULTIMA is the company's most successful amplifier in its 30-year history and is based on three decades of amplifier manufacturing experience by Chord Electronics. It uses an entirely new circuit topology, the first completely new design since those early years.

The new dual-drive amplifier technology is an advancement of Dr. Malcolm J Hawksford's technical work and has been developed by Bob Cordell of Bell Labs. The ULTIMA includes next-generation amplifier technology, with advanced dual-drive topology and advanced concepts from John Franks in ultra-high-frequency power supplies.

The ULTIMA amplifier features 64 proprietary MOSFET pathways that require the most advanced and sophisticated driving circuitry, free from elements that degrade sound. The driving circuitry features an ultra-low-distortion, high-voltage amplifier operating at very high speed: 300 volts per microsecond.

The ULTIMA offers 780 watts into 8 ohms, 1,400 watts into 4 ohms, and 2,500 watts into 2 ohms. The maximum current output exceeds 500 amps, offering stunning dynamics and fidelity.
