Description

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 Étude 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.
