LTA is excited to announce the Z10e Electrostatic Headphone Amplifier. With all the magic, realism, and 3D soundstage of ZOTL technology, the Z10e delivers one of the best electrostatic headphone experiences available. In addition, the Z10e is a full function regular dynamic and planar headphone amplifier and a 12-watt per channel integrated speaker amplifier.

A single component solution, the Z10e incorporates the acclaimed ZOTL10 power amplifier, a Berning-designed preamplifier, and the LTA control system with 100 steps of attenuation and 5 true balanced and single-ended inputs – all packaged in a beautiful aluminum low-resonance case designed by Fern & Roby.

With startling realism, plentiful bass, and gorgeous mids and highs – 3D music seems as if it’s appearing from a silent, black background.

The LED array display and the milled aluminum front and rear panels exude high quality manufacturing, handmade in the USA.

The Z10e offers all the benefits of the ZOTL technology of three times the tube life and one third the heat output.

The Amplifier

The heart of the Z10e is the highly-acclaimed ZOTL10 power amplifier, using sweet sounding EL-84 power tubes providing 12 tube watts per channel. Delivering much higher power than solid state amps with the same power rating, ZOTL tube amplifiers can drive your 90db and above sensitivity speakers to very loud, even “thundering” levels.

The Preamplifier

The amplifier is preceded by the 12AU7 preamplifier circuitry, which was borrowed from one of David Berning’s ultra-premium amplifiers. It features both true balanced and single ended inputs. The preamplifier uses ceramic circuit board material, giving it a premium point-to-point sound quality.

The LTA Control System

The amplifier is wrapped in our new control system featuring: 5 inputs (including one true balanced input), tape in and out, LED dimmable display with configurable time out, LED input indicators, home theater mode, remote controlled stepped attenuation using premium Vishay Dale resistors, and a linear power supply configured with a Belleson regulator for extremely low noise. Additionally, the Z10e comes equipped with two headphone output jacks: a high output for less sensitive headphones and a low output for very sensitive headphones.
