CHORD ELECTRONICS Ultima 6 Power Amplifier

Innovative clean-power technologies and custom components within our stereo power amplifiers are what have propelled the Chord ULTIMA series to legendary status in and outside the recording studio. Their ability to instantaneously react and deliver sheer power, whilst maintaining transparency and incredibly low distortion leaves you with nothing but a masterpiece.

Chord Electronics Ultima 6 Power Amplifier

The ULTIMA 6 currently offers the most affordable way into our next-generation ULTIMA family of stereo power amplifiers. It builds upon its award-winning predecessor, the SPM 1050 MK II, adding our ground-breaking next-generation ULTIMA amplifier topology.

The new 180-watt model, which benefits from John Franks’ ground-breaking dual-feed-forward circuit delivers a lightning-fast response coupled with effortless power for astonishing dynamics and timing, delivering unrivalled fidelity.

30-years-in-the-making, our new dual-feed-forward topology offers breakthrough performance and is our first all-new circuit in three decades. ULTIMA amplifiers have been engineered for the very finest hi-fi systems; ULTIMA is the ultimate expression of the finest high-performance, ultra-fast, high-power amplifier technology available today.

The ULTIMA 6 has an incredible 16 proprietary MOSFET power devices which demand the most advanced and refined drive circuitry, featuring an ultra-low-distortion, high-voltage amplifier operating at very high speed: 300 volts per microsecond.

Our TO3-style dual-die lateral-matched MOSFETs are continuously monitored with output stage error-correction circuitry and feature fully balanced input circuitry with DC-tracking servos and full temperature compensation.

ULTIMA  6 shares the same DNA as the flagship and reference-level monos, yet benefits from greater practicality and affordability, due to a differing power output.

Our renowned aircraft-grade solid aluminium casework offers a reassuringly high-end and entirely non-resonant enclosure for the electronics and is presented with a redesigned 28-mm-thick fascia featuring John Franks’ latest aesthetic.

A recessed spherical polycarbonate power button illuminates for standby and operation modes and a discreet, hidden front panel switch, located in the vertical split line, enables dimmable lighting.

The amplifier’s rear panel contains both balanced and unbalanced connections, high-quality loudspeaker terminals, a 12 V trigger and a C-19-type IEC.
