A.N.T. Audio Amber 3T User Manual

A.N.T. Audio "Amber 3T" headphone amplifier
Building upon the success of the award-winning A.N.T. Audio Kora 3T phono stage,
new Amber 3T headphone amplifier uses the same FET-only, class A, single-ended
philosophy. Suitable to use with headphones from 25 to 300 Ohm impedance and a
variety of line-level sources, the Amber 3T provides an excellent sound quality in a
small package. Two versions of the headphone amplifier are available:
The Classic
(Green
FM series for output and power supply capacitors and comes with a switch-mode
univoltage power supply.
The Special Edition
Velvet volume potentiometer, user adjustable FET biasing, upgraded ELNA Starget
output capacitors and comes with a switch-mode univoltage power supply.
The Special Edition Plus
comes with a high quality linear power supply.
