LTA MicroZOTL 2.0 DELUXE with Linear Power Supply

Headphone Amp & Pre-Amp designed by David Berning

A Class A tube headphone and pre-amplifier, utilizing the patented ZOTL output transformer-less technology that eliminates the transformer distortion and noise.

Class A Pre-amplifier

1 watt per channel output

Drive speakers, 89db or higher sensitivity

    Utilizes a highly refined, no feedback, Class A triode design coupled with the ZOTL circuitry.
    The power supply is in a separate enclosure for extremely low noise.
    Has a 1 watt per channel output that can easily drive headphones, including low-efficiency electrostatic and planar types.
    Has outputs that enable it to drive tube amplifiers as a Class A preamplifier.
    Gold contacts in all audio path connectors, silver coated copper teflon insulated wiring, hand wound coils and impedance converters, and 100% manufactured in Washington D.C.
    The top of the unit is transparent so that you can see the beautifully constructed circuitry and four vacuum tubes
    External power supply - extremely low noise floor
    Easily drives low efficiency electrostatic and planar headphones
    Eliminates intermodulation distortion that is inherent in all transformer designs
    Simulates the correct transformer turns ratio using impedance converter
    Two selectable inputs
    The vacuum tubes have no adjustments and should provide more than 10,000 hours of tube life
    Automatic universal power supply allowing it to be used in any country.
    Low impedance output easily matches wide range of speakers and headphones
    No heavy power or audio transformers– unit weighs only 5.3lbs or 2.5 kg
