The multi-award winning Chord Electronics Choral family welcomes Etude, a 150W Class AB stereo power amplifier featuring the first fundamentally new topology since the inception of Chord in 1989.

Although the amplifier is conservatively rated at 150W into 4ω, run Etude in bridged mono mode and this can be increased to 300W into 4ω.

Aerospace Technology

Using highly advanced technologies seen within the aerospace industry, Etude has been designed to compliment and exploit the full potential of the multi-award winning Dave DAC (which has preamp functionality) and the brand new topology has even faster power delivery than exiting designs. This offers unrivalled dynamics, life-like delivery of transient information, and effortless control over loudspeaker drive units.

High Power

Etude is based upon multi-feedback and dual feed-forward error-correction amplifier technology that intelligently adjusts and compensates the individual linearity of the 250-watt lateral structure high-power proprietary MOSFETs.

Crystal Clear

Internally there are three individual high frequency switch mode power supply units, one for each active power rail and a final for the auxiliary rails. When paired with advanced internal shielding, active cooled plenum chamber design, and custom Chord MOSFETs, you have Etude – a world-class, extremely fast, crystal-clear amplifier.
