Esoteric announced the A-100, a triode tube based power amplifier. This flagship tube power amp incorporates the Esoteric's latest technology, it features a proprietary circuitry designed to enhance the audio quality.

Tha A-100 delivers 2x 45W from 4x KT-88 tubes in UL-push/pull. The VBS technology compensates the fluctuations in bias voltage and the ZVS circuit stabilizes the cathode follower DC output level to improve operation of direct-coupled circuit components for a better linearity. The Esoteric A-100 also works as an integrated amplifier by selection on a switch between Direct or Line In input.

This power amplifer weighs "only" 40kg and comes equipped with a remote control, it will release in February this year at a price of $19,000.
