Janus

Janus is a full-function all-tube preamplifier with six line level inputs and one phono input. Janus represents the key features of Rhea phono stage and Calypso linestage combined into a single chassis. All tube amplification and output, a fully balanced linestage, discrete switched resistor volume control, versatile single-ended and balanced inputs and outputs, and dual-mono audio boards are all part of Janus. The full function remote controls all preamp and phono functions, including gain, loading, absolute phase and the internal demagnetizer. True to its Saturn Series heritage, the build and sound quality of Janus have won it global praise, including 2010 and 2011 TAS Editor's Choice Awards.
