Aesthetix IO Eclipse

Jupiter Series Eclipse Reference Two Box Phono Preamplifier

Io is an all-tube phono stage suitable for the most demanding cartridges including low-output moving coils. A proprietary differential circuitry design achieves high gain with extremely low noise. A separate power supply chassis removes any possibility of transformer noise corrupting delicate audio circuitry. Peter Moncrief Stealth Capacitors are used in the Eclipse Edition for unparalleled sound quality. An optional innovative mechanically-switched discrete resistor volume control yields precise resolution at all listening levels.

• High gain / low noise capable of handling low output moving coils.
• Zero feedback.
• 80dB maximum gain, internally selectable down to 56dB.
• Flexible user selectable loading on the back panel from 47Kohms down to 10ohms.
• All tube amplification and output (16 tubes total).
• Separate vacuum tube regulated power supply utilizing 8 tubes.
• Two sets of XLR and two sets of RCA outputs per channel.
• Input can be either RCA or XLR.
• Optional: Innovative and unique mechanically switched discrete resistor volume control with 46 positions using Roederstein resistors, one for each channel.

Io is available in three versions: Mk II, Signature and Eclipse. 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 Io, incorporating constrained-layer damped machined aluminum panels and Peter Moncrief's Stealth Capacitors. All versions of Io can be factory upgraded to Signature or Eclipse.

Jupiter Series Io and Callisto are available in (and factory upgradable to) an Eclipse Edition. The Eclipse transformation takes already industry standard setting products to a whole new level of performance. Io, Callisto and their respective power supply receive enhanced internal parts, improved chassis construction, and stunning customizable casework.

StealthCap Capacitors

Musical signals passing through a capacitor are blurred or clouded as signal reflections bouncing off the capacitor plate corrupt the original musical signal. StealthCap capacitors created by Peter Moncrief aim to cure this problem by dramatically reducing reflections along the capacitor plate. The "Stealth Technology" is made possible by a combination of laborious precision handiwork and costly exotic materials including new conductors, dielectrics, and composite resins. The resulting signal has a quieter background, rich and detailed spatial imaging, time focused musical coherence, and a broader more impactful dynamic range. The Io Eclipse uses eight .22uF / 600v Stealth coupling capacitors made of exotic copper foil. These are used between the second and third gain stages, and the third gain stage and output stage. The Io and Callisto Eclipse output stages also use eight 4uF / 400v Stealth capacitors in a unique balanced configuration.

Chassis Construction

Eclipse Edition chassis feature an extremely rigid and acoustically damped design, delivering new levels of articulation and clarity. Three separate side and top panels are machined from aluminum billet. Each panel is constrain layer damped with advanced 3M adhesives, requiring a labor intensive application of heat and pressure for proper mating. Advanced interlock material and machine screws are used to attach the panels for easy tube access. Harmonic Resolution Systems Nimbus Couplers, specially made for Aesthetix, are used to intimately couple the chassis with the equipment rack, greatly reducing mechanical noise.

Casework Design and Customization

Eclipse editions feature a stunning multi-piece front panel which includes detailed machining of the front panel casing, inlay and logo. Jupiter Eclipse customers may personalize the appearance of their unit by selecting metal finishes for the faceplate, rings, knobs, dials and logo.
