The line stage circuit is the same transformer- coupled Class A1 balanced triode design found in the Statement Line Stage. The external power supply has dual-mono recti cation and ltering of the crucial high voltage supplies for superb, spacious imaging and great preservation of nuance. The remote volume control is of the direct-acting analogue type and continuously variable, so you easily can the precise level that makes the music snap into focus.

The audio connectors are premium rhodium plated Cardas and Neutrik Professional. There are three high level inputs, two of which may be balanced or single-ended, just like the output.

Vinyl lovers may specify the optional MM MC phono stage, which features three twin triodes operating in pure Class A1, variable MC impedance loading, and purely passive, precise RIAA equalization. The circuit topology is derived from the Signature Mk IIa SE, di ering principally in the number of tubes employed, and uses the same premium MC input transformers. The results rival and exceed those delivered by many more costly separate phono stages. You should expect nothing less of a VAC.
