The Choral Étude 150w Stereo Power Amplifier 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 150w Stereo Power Amplifier in bridged mono mode you can increase this to 300W into 4Ω.
