The latest amplifier design by David Berning. Striking a balance between triode and pentode mode, the new ZOTL Ultralinear+ amp provides the unique advantages of each while maintaining all the benefits of the ZOTL circuitry.

The ZOTL Ultralinear+ amplifier delivers uncolored detail and realism without sacrificing natural mids and powerful, controlled bass. The ZOTL Ultralinear+ is our most detailed and refined amp. Many listeners compare the presentation to SET amps, while offering much more power.

Listeners enjoy the less forward, distortion-free presentation that is “more pleasing to listen to” the Ultralinear offers.
