About the 300B SET ZOTL 2020

The Berning 300B SET ZOTL Balanced 2020 version is a high-end audio amplifier designed by David Berning that employs his patented ZOTL (Zero Hysteresis Output Transformer-Less) technology. This amplifier delivers approximately 30 watts per channel in a single-ended triode configuration using 300B tubes, known for their rich midrange and musicality. The ZOTL technology enables faithful amplification with very low distortion, automatic biasing for various tube combinations, and a constant output impedance across the audio spectrum. The balanced 2020 version features balanced inputs for improved noise rejection and signal integrity. It is highly regarded for its ability to reveal subtle harmonic details and spatial attributes of music, making it ideal for chamber music and other midrange-rich genres. The amplifier operates coolly and reliably with low weight and tight regulation, and it is hand-built with high-quality components and craftsmanship. The design also includes sophisticated speaker protection and is optimized for high-efficiency speakers. This amplifier is considered a reference-level SET amplifier with a unique blend of triode warmth and modern dynamics, delivering a transparent, detailed, and dynamic listening experience.
