Chord Electronics BerTTi

Compact Stereo Amplifier
Bringing 2 x 75 Watts pure ULTIMA power into the Table Top range the new BerTTi offers incredible UTIMA sound to complement the mighty processing power of Chord Electronics DACs.
ULTIMA amplifier technology was developed by John Franks based on a scientific research of dual error correction schematics presented in the published works of John Cordell and, later, of Malcolm J. Hawksford. Essentially it's a tremendously high speed monitoring system which corrects the amplifier output using both feedforward and feedback strategies. To implement ULTIMA John Franks designed custom MOSFETs which are manufactured exclusively for Chord Electronics. ULTIMA technology is this innovative error correction combined with Chord Electronics high speed power supplies perfected since the company's first amplifier. The result is unrivaled sonic performance for such a compact chassis, 2 x 75 Watts (8 Ohm) of cleanest power to amplify your music.
Chord Electronics Hugo TT2 DAC/preamp is a natural companion for BerTTi, and by adding the Hugo MScaler processor the owner will have a clear upgrade path to upscale audio to 705.6 kHz, 16x CD’s native resolution, which makes the three-box system truly class-leading.
