Io Signature Version £8,100.00

Signature, released in 2001, was the first major step forward for the Io and Callisto. Incorporating improved componentry such as Dynamicaps from Peter Moncrief and hand tuning the individual gain stages, greater resolution and inner detail were achieved without sacrificing the richness and dynamic bloom of the original design. 

The Signature version uses custom-made inter-stage Teflon coupling capacitors, replacing the polypropylene units, between the 1st and 2nd gain stages. This change results in very high resolution of the very low signal level. Between the 2nd and 3rd, and 3rd and 4th gain stages (4 total per channel), the standard Rel-Caps are replaced with .22uF Dynamicap. The change in these capacitors results in higher resolution, extension, less grain and more air. The 2uF output coupling capacitors (4 per channel) are also 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 "tweek" each unit to a rigid standard.
