HIGH QUALITY PARTS AND SOUND
Carefully selected high-quality components of audio grade are employed for the main circuit and greatly improved the tone quality. High-quality relays are placed close to the input terminal to realize the shortest signal path, and the mutual interference between equipments is eliminated by switching the hot / cold side of the signal simultaneously. Also the circuit constant has been looked over again in detail.
The balanced input via XLR terminal along with the custom-made double axis 4-gang volume controller enabled a full-balanced operation from input to sound element drive.
CLASS A AMPLIFICATION
Class-A all-stage DC amplifier circuit configuration eliminated coupling capacitors throughout the signal path. High-voltage dual triode 6FQ7 / 6CG7 are employed in the output stage, and the input stage features a simple two-stage amplification using low noise FET that are hand selected.
3 PAIRS OF INPUT TERMINALS
One stereo XLR input is equipped to connect directly to the XLR balanced output of a high-class CD/SACD player. Also, two pairs of RCA inputs enable the unit to switch between connected source equipments. One of the two RCA inputs has a bypassing output that, for example, can be connected to your integrated amplifier for flexible system-up.
