Tsakiridis Devices Artemis Ultra

Artemis Ultra is a power amplifier in dual-mono configuration.
It’s design is a push-pull configuration implementing 2 power tubes per channel in class AB1 operation.
All electronic components are through hole type soldered by hand.
Artemis Ultra utilizes our 8 layer handmade output transformers with high quality core for superb sound quality.

The push – pull configuration of Artemis Ultra draws enough power from the output tubes to drive a wide range of loudspeakers. Gold plated RCA connectors are implemented for the signal input and WBT-703 Next Gen binding posts for the loudspeakers.
Carefully selected values and types of the electronic components contribute to the reliable circuits operation and the high sound quality of the amplifier. Metal film power resistors and Jantzen superior-Z signal capacitors are used in Artemis Ultra. The meticulous PCB design ensures excellent behavior in SNR, distortion and channel separation.
Inner signal wiring with high quality shielded signal cable. Power wiring uses high quality copper cables of more-than-needed AWG gauge, to achieve low impedance power transfer. All power cables are twisted in pairs to minimize the electromagnetic interference.

The handmade multilayer output transformers allow the amplifier to reveal the sound stage and all the music details through the entire audio spectrum.
Made by us and tested thoroughly for quality and reliability.
The same applies to the power transformer. The positioning of the transformers is such that minimizes the magnetic coupling between power and output transformers.
