BerTTi Amplifier

BerTTi is a fully balanced 75-watt stereo power amplifier benefitting from the latest ULTIMA dual-feed-forward topology. Extending the range of ULTIMA-technology Chord Electronics amplifiers, BerTTi makes full use of advanced error-correction technology which monitors and immediately corrects signals before the output stage for astonishing accuracy and unrivalled fidelity from a compact-chassis device.

BerTTi features both balanced and unbalanced inputs, high-quality gold-plated loudspeaker outputs, plus a 10 A IEC power inlet. Further features include two modified power supplies for increased performance, plus an additional auxiliary power rail for the front end, which provides extra voltage to drive the custom-made MOSFETs.

British-built, BerTTi brings the next-generation ULTIMA topology to the ground-breaking Table Top (TT) range. When combined with the resolving power of the award-winning Hugo TT 2 DAC/preamp, the duo offers new levels of sonic performance from a small system. The addition of the Hugo M Scaler upscaler, with the ability to upscale audio to 705.6 kHz, 16x CD’s native resolution, makes the three-box system truly class-leading.
