The Calysto

 

The Calysto is designed for ultimate fidelity. It features a wider 'Class A' operating region in the output stage, providing exceptional resolution in the upper-midrange and high frequencies at low output power levels.

The Calysto is especially suited to driving the Mid/HF channel amplifier in a high-performance split system. Front panel design and footprint are compatible with the Apollo, Athene and Artemis, allowing amplifiers to be stacked.
