-Original low noise dual FET at first stage as well as all stage direct coupling Class A DC amplifier configuration with no coupling capacitor has realized natural tone quality with large amount of information.
-Further improved emitter follower at output stage has enabled wide range reproduction resulting in both the extended dynamic range at high frequency and improved over all tonal quality.
-In addition to RCA input terminal, XLR balanced input terminal has been added to provide connection to wide range of audio equipment.
-Custom made 2 axis 4 gang volume control
-Extravagant non-magnetic aluminum alloy chassis
-Components with little aging characteristics are hand selected for tonal quality and performance
