Mark Schneider founded Linear Tube Audio in 2015. Coming from an extensive engineering career that included management, manufacturing, and product design – including being the architect behind the fastest document scanner in the world – Mark was forced into an early medical retirement. After a remarkable, multi-year recovery, he decided to commit himself to the passion that started a long time ago with a pair of 3-panel Magnepans, a Thorens turntable with an SME arm, and some SAE amplifiers.

Since the debut of ZOTL technology, no one else has been able to successfully manufacture David Berning’s complex designs. It was this uniqueness and complexity that attracted Mark to producing ZOTL amplifiers specifically, in addition to their spectacular sound. Each amplifier requires hours of hand-building, which is currently done by Mark and his team in LTA’s Washington, DC workshop. David Berning personally reviews initial units to ensure that the build quality meets his extremely high standards.  

Due to its continued high demand 8 years after production ended, Mark decided to have Linear Tube Audio debut by introducing an improved version of David Berning’s original MicroZOTL, the MicroZOTL2.0. For the amps following, Mark and David have worked collaboratively, with David designing the core amplifier circuitry to Mark’s specifications, and LTA creating the rest of the unit.
