The Signature’s line stage has no coupling capacitors to detract from the purity and detail of the hand-wired circuit. With no loop feedback, the output is stable and free from dynamic interactions with the load. Six standard line inputs (five when phono is fitted) are present, as well as a fully balanced Cinema Bypass input.

The optional six-tube phono stage is sensitive and quiet, compatible with low-output, moving coil cartridges. Gain is adjustable, as is resistive loading. Electrostatic decoupling prevents the heater circuits from “talking” to each other, a common cause of lost detail. A separate power transformer is used, eliminating any disturbance of the delicate phono signal by the powerful line stage.

The VAC logos are backlit in an elegant blue in normal operation, and display red when the mute is activated. These are set in the heirloom-quality sculpted 3/8” faceplate.
