Callisto es un previo de linea a válvulas realizado para los clientes que exigen a sus equipos lo máximo. Circuito Balanceado Puro desde la entrada hasta la salida consiguiendo un sonido realmente limpio. Un circuito de volumen basado en resistencias que maximizan la resolución a cualquier nivel de sonido. Una fuente de alimentación separada evita cualquier tipo de interferencia que estropee la señal sonora. Peter Moncrief Stealth Capacitors son empleados en la edición Eclipse Edition consiguiendo una calidad sonora sin precedentes.


Descripción del Producto


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.


Mk II, Signature and Eclipse
Callisto is available in three versions: Mk II, Signature and Eclipse (see tabs above for more detail on each version). The Mk II version uses high-grade Rel-Cap polypropylene coupling capacitors. The Signature version uses exotic and expensive coupling capacitors and other critical parts to bring the performance to a higher level. Eclipse is the ultimate realization of the true capabilities of the Callisto, incorporating constrained-layer damped machined aluminum panels and Peter Moncrief’s Stealth Capacitors. All versions of Callisto can be factory upgraded to Signature or Eclipse.

Dual Power Supply
Callisto comes with a single power supply standard, or optionally a second power supply may be added for true dual-mono (see “Power Supply” tab above for more detail).

Remote Control
Remote control is optional with the Callisto. Adding the system allows remote adjustment for volume and muting, and optionally phase. The remote system uses motors and pulleys to rotate the volume controls and has a completely isolated electrical system. It may be added to any version of Callisto (see “Remote Control” tab above for more detail).

Faceplate Finish
Callisto Mk II and Signature available with black or silver faceplate.

Simply phenomenal inner detail, vast soundstaging, and a dynamic and harmonic bloom that seems to bring every kind of music to vivid lifeThe Absolute Sound Golden Ear Award (2003, CALLISTO SIGNATURE linestage and IO SIGNATURE phono stage)

The Callisto is as fast, neutral, dynamic and authoritative as any preamp I’ve ever heard, solid-state or not… entirely worthy of the high esteem in which it’s been held…” -Shane Buettner, Audio Perfectionist Journal (2007, CALLISTO linestage)

In practice, (the remote) is a marvel to use and makes listening to music a joy.” -Albert Porter, (2006, CALLISTO linestage with remote), read review

stunning dynamics, remarkable transparency, and a life-like recreation of space and volume… jaw-droppingly three-dimensional” -Wayne Garcia, The Absolute Sound (2002, CALLISTO linestage) “Centerstage” and “Harry Pearson’s Workshop” feature.
