Callisto is an all-tube linestage suitable for the most demanding audio systems and listeners. Fully balanced circuitry from input to output, including internal balancing of single-ended inputs, results in common mode signal rejection and cleaner sound. The innovative discrete switched resistor volume control maximizes resolution at any listening level. A separate power supply chassis removes any possibility of transformer noise corrupting the delicate audio circuitry. Peter Moncrief Stealth Capacitors are used in the Eclipse Edition for unparalleled sound quality.

• Fully balanced differential circuitry with ability to internally balance a single-ended input signal.
• Innovative and unique mechanically switched discrete resistor volume control with 46 positions using Roederstein resistors.
• Separate volume controls and input selectors for each channel.
• All tube amplification and output (8 tubes total).
• Separate vacuum tube regulated power supply utilizing 8 tubes.
• Two sets of XLR and two sets of RCA outputs per channel.
• Six inputs: First two single-ended (rca) or balanced (XLR); remaining four single-ended (rca) only.
