Aesthetix Calypso Pre

Calypso er en rørforforstærker som er velegnet til lyd- og hjemmebiografsystemer. Fuldt afbalanceret kredsløb fra indgang til udgang, herunder intern afbalancering af single-ended indgange, resulterer i common mode signalafvisning og renere lyd.

CALYPSO SIGNATURE

The Signature version uses custom-made inter-stage Teflon hybrid coupling capacitors, replacing the polypropylene units, between the gain stage and output stage (2 per channel). The change in these capacitors results in higher resolution, extension, less grain and more air. 

The 2uF output coupling capacitors (4 per channel) are replaced with 4uF Dynamicaps. This change provides more drive, bass extension, resolution and dynamics while also reducing grain. Highly specialized adjustable air-core capacitors, used primarily in the radio-frequency realm, are installed and adjusted to "tweak" each unit to a rigid standard. The five rubber feet are replaced with Harmonic Resolutions Systems' Nimbus Couplers specially made for Aesthetix (Earlier Signature Saturn pieces did not incorporate this, please contact Aesthetix for this free upgrade if you have an earlier Signature piece without the Nimbus Couplers). This change results in a lower noise floor and more air and space. 

The cost of these specialized parts alone is about 1/4 the manufacturing cost of a brand new unit! Any tubes that can be bettered by our special stock of graded and matched tubes are replaced. Any other improvements needed to make the unit current are installed, including software updates, etc. A new lens with "SIGNATURE" stenciled is installed. Each Signature unit undergoes rigorous test procedures and listening.

NEW CALYPSO ECLIPSE

First phase: Internal changes to the Calypso start with .22uF / 600v Stealth coupling capacitors used between the gain stage and output stage. Four total of these exotic capacitors are used.

There are four 2uF / 400v coupling capacitors used in each channel of the output stage of the Calypso. In the Eclipse version, these are replaced with Stealth copper foil 4uF/400v, improving low frequency response.

Second phase: High frequency tuning capacitors are installed and hand-adjusted to tailor the frequency response to a tight .1dB standard (as also found on our Signature version).

Third phase: The high voltage transformer, heater transformer and high voltage choke are all re-installed on isolation mounts. Harmonic Resolutions Systems' Nimbus Couplers specially made for Aesthetix replace the four rubber feet of standard units (as also found on our Signature version). The new power supply is installed with enhanced ventilation. Additional damping material is added to key chassis points.

Fourth phase: A single point ground system is used to ground the transformer cases as they are no longer electrically grounded to the chassis via physical contact due to their isolation mounts. All Eclipse Rhea, Calypso and Janus units receive a new power supply, which has been refined by improved trace routing to further reduce extraneous noise.
