Product Description

Featuring technology derived from the aerospace industry, the Chord Electronics Étude amplifier is an incredibly compact stereo amplifier with stunning power, speed and clarity.

The multi-award winning Chord Electronics Choral family of products has never sounded so good. Welcome Étude to the table, a 150w Class AB stereo power amplifier featuring the first fundamentally new topology since Chord Electronics’ inception in 1989, using highly advanced technologies seen within the aerospace industry.

The Choral Étude has been designed to both 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, offering unrivalled dynamics, life-like delivery of transient information, plus effortless control over loudspeaker drive units.

The design for Chord Electronics Étude amplifier 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. 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 Electronics MOSFETs, you have Étude, an world class extremely fast crystal clear amplifier.

Although the amplifier is conservatively rated at 150W into 4Ω, if you run Étude in bridged mono mode you can increase this to 300W into 4Ω.

Chord Electronics

Engineering without limits means uncompromising standards for Chord Electronics. The British professional audio company took flight in 1989 when founder and Chief Engineer John Franks found inspiration in his junior engineer job at an avionics company. Aviation electronics demands reliability, performance, and superior attention to detail. That’s exactly what Franks brings to Chord's digital products. His comprehensive knowledge of power supply design and an ethos of doing things ‘right’ regardless of cost and effort sets Chord apart from competitors. This is reflected in the new and innovative Hugo M Scaler upscaling component.

The BBC received the first Chord amplifiers, followed by world-leading artists and studios, including Abbey Road, Sony Music (New York), and The Royal Opera House. Chord’s audio prowess generated demand for a domestic range. This audiophile-approved range encompasses the design, engineering and build standards the finest professional equipment requires. Today, Chord applies proprietary technologies to all of its British-made products. As a result, you can expect studio-grade audio performance across the entire Chord range encompassing amplifiers, DACs and music streamers from the Mojo 2 to the DAVE DAC.

As a nationally recognized leader in the field of high-end audio and home theater, Overture is a proud dealer of Chord Electronics products. We sell customers the best DACs and music streamers from Chord. Interested in purchasing a new Chord Electronics product?
