Chord Electronics BerTTi silver

Introducing the Chord Electronics BerTTi

The Chord Electronics BerTTi is a fully balanced 75W stereo amplifier, featuring the dual-feed ULTIMA topology. This advanced error-correction technology monitors and immediately corrects signals before the output stage, ensuring unrivaled precision and sonic fidelity.

British Design and Engineering

Meticulously crafted in England, the BerTTi is the result of artisanal expertise and cutting-edge engineering. Its compact chassis is precision-machined from aerospace-grade aluminum, offering an elegant and modern aesthetic. Available in silver or black, it seamlessly integrates into any listening environment.

Connectivity and Performance

The BerTTi features balanced and unbalanced inputs, as well as high-quality gold-plated speaker outputs. Two modified power supplies enhance performance, while an additional auxiliary power rail for the front end provides extra voltage to drive the custom MOSFETs. These features ensure a dynamic and transparent sonic experience, capable of driving speakers ranging from compact models to the most challenging to power.

Compatibility and Expansion

The BerTTi is designed to work optimally with the Hugo TT 2 DAC/preamp/headphone amp and the Hugo M Scaler upscaler. This combination delivers world-class sound performance, with the ability to upscale audio to 705.6kHz, 16 times the native resolution of a CD.
