Linear Tube Audio ZOTL Ultralinear
Best transparent amplification for discerning audiophiles seeking sonic purity.
The Linear Tube Audio ZOTL Ultralinear amplifier, designed by David Berning, redefines tube amplification with its patented Zero-hysteresis output transformerless (ZOTL) technology. This innovative design allows it to utilize unique 17JN6 tubes, delivering 20 watts per channel with exceptional accuracy, detail, and realism. It offers the liquidity of tube tone combined with the clarity of solid-state, all while generating less heat and providing significantly longer tube life (10,000-20,000 hours). The advanced switching power supply and a super-wide frequency response from 8Hz to 60kHz ensure it plays nicely with all speakers, featuring a sophisticated speaker protection system for added safety. The casework, by Fern & Roby, is crafted from aluminum, exuding premium build quality.
