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.
Super condition trade-in Aesthetix Callisto Tube Linestage with external power supply unit.
Linestage comes in original box with printed owner’s manual, power cord, and connecting umbilicals.
Units are rated a conservative 7/10 for minor cosmetic wear consistent with age and use including: a small scratch on the front of the power supply and one screw (left rear) with stripped threads, also on the power supply.

Outputs: 2 RCA (SE) and XLR (balanced), 1 tape RCA
Line level gain: 23 dB single ended (SE), in/out, and 29 dB balanced/out
Volume control: switched resistor network volume control with 46 steps
Front panel controls: Left and right input select, left and right volume
Frequency response: +- 0.25 dB, 20 Hz - 20 Khz
Signal to noise: measured at 70 dB minimum, A-weighted (ref 1 mv input, 75 dB gain setting)
Line input impedance: 100K ohms SE, 200K ohms balanced
Output impedance: 1K ohms SE, 600 ohms balanced
Recommended amplifier load: 10K ohms or greater (SE), 20K ohms or greater (Balanced)
