The gem of the Ithaka concept is the output stage. It is based on our latest generation of TriodeFet technology (the specific TF generation is only used in our top-end SE amplifier, QuintEssence).
Kassandra Signature LE is a digital-to-analog converter with a tube output stage. The conversion is carried out using 12 parallel connected AD1865N-K chips per channel, which are multi-bit converters with R-2R matrices with a resolution of 18 bits (24 R-2R matrices); an external power supply unit with rectifiers on gas burners, 5 toroidal transformers and a large capacity storage capacitors.The parallel connection provides higher linearity and reduced noise.
The gem of the Ithaka/Ithaka minor concept is the output stage. Unlike the larger Ithaka model, the Ithaka minor uses Gen1 TriodeFet technology. This particular generation of TriodeFet is the same as in our Essentia and Aperio amplifiers, with some modifications.
The Aries Cerat Kassandra 2 Sig uses eight discrete low-noise regulators, and uses a system of four powerful power supplies based on toroidal transformers. The output stage is powered by an E280F lamp. Via USB, the Aries Cerat Kassandra 2 Sig can receive signals up to PCM 24/384.
Digital-to-analog converter with lamp output stage. The conversion is carried out using 8 parallel connected AD1865N-K chips per channel, which are multi-bit converters with R-2R matrices with a resolution of 18 bits (16 R-2R matrices).
