Chord Electronics Launches ULTIMA-tech BerTTi

New BerTTi offers ULTIMA tech for less and elevates the TT range

1 June 2023, Kent, England: Chord Electronics has launched its most affordable ULTIMA-technology stereo power amplifier to date, BerTTi (£3,995). The new power amp also introduces the company’s next-generation ULTIMA topology to the ground-breaking Table Top (TT) range, home to the Hugo TT 2 DAC/pre/head amp and Hugo M Scaler upscaler.

BerTTi is a fully balanced 75-watt stereo power amplifier benefitting from the latest dual-feed-forward error-correction topology. First unveiled at HIGH END, Munich, 2023, BerTTi directly replaces its predecessor, the TToby, and expands the British built ULTIMA-topology range amplifiers designed by Chord Electronics owner and founder John Franks. Franks’ advanced ULTIMA error-correction technology monitors and immediately corrects signals before the output stage for astonishing accuracy. 

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.

BerTTi follows a line of highly advanced full-width ULTIMA-technology power amplifiers, including the original flagship ULTIMA mono power amplifier (780 W), the successive ULTIMA 2 (750 W) and 3 (480 W) mono power amplifiers, the ULTIMA 5 (350 W) and 6 (180 W) stereo power amplifiers and in May 2023, the new ULTIMA INTEGRATED. 

BerTTi’s sleek metalwork is precision-machined from solid aircraft-grade aluminium and is available in a choice of Jett Black or Argent Silver.
