Chord Electronics BerTTi

Chord Electronics 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.

Key features and benefits

75 W into 8 Ω – A powerful 75 W into 8 Ω tabletop amplifier, created with trickle-down Ultima technology.

Fully balanced XLR and single-ended RCA inputs – BerTTi can be sited away from its natural partner TT2 or other input sources (e.g. DAVE) with long cable runs using XLR with no signal loss.

This enables short speaker cable runs between BerTTi and loudspeakers.

High-frequency switch-mode power supply (SMPS) – Dispensing with noisy toroidal transformers that impact the audio spectrum, BerTTi employs a dual SMPS operating at a very high frequency, well outside the audio bandwidth.

Proprietary MOSFET output transistors – Left and right channels behave identically.

Close matching of their proprietary MOSFET devices, ultra-low distortion operating at high speed, gives an overall better performance than ‘off the shelf’ solutions

Compact design – Part of the TT range, BerTTi is easily accommodated into all environments for high performance from a small footprint
