Commentary

Professional type preamp with thin yet low impedance balanced output.

A fully discrete design is used for the circuit configuration.

In addition to the RCA unbalanced outputs, there are also XLR3 balanced outputs.

The independent design of the power supply unit reduces interference from the power supply unit.

There are 2 color variations of black and silver.

There was a separate phono equalizer amplifier module for MM/MC as an option sold separately.
