Synthesis Action A40Virtus 40W Integrated Stereo Tube Amplifier

USB & S/PDIF input
For the first time we include an onboard 24Bit 192KHz Wolfson DAC for a extraordinary listening experience.
DC Powered tube heater
Ali tubes, except KT66, have DC stabilised heater circuits to reduce hum noise to a near in-audible minimum.
Output transformer
The Output transformer uses a Hi-Grade lron-Silicon for superb frequency reproduction & width. With this newly designed custom output transformer unique to the A40Virtus we are able to achieving a highly delicate & precise sound reproduction faithful to the originai recording.
Mechanical chassis construction
The power supply & output transformers are held by an extremely rigid "H" structure that keeps the unit free from unwanted vibrations which further helps reduce unwanted noise to the tubes.
Remote control
Featuring a superb CNC machined case it has a soft button design, perfectly matching the aesthetics for the "ACTION" series.
Feet
Four CNC machined aluminium feet with an insert of natural rubber. The depth & form of these rubber feet has been calculated to minimise vibrations of the amplifier in isolation from its surroundings.
Binding posts
Gold plated professional binding posts for a continued oxidisation free connection further improve sound refinement.
Sockets
Gold plated ceramic sockets for a continued oxidisation free connection further improve sound refinement.
Components
Components for the A40Virtus have been selected with great care throughout. Only the best available components are considered & all must undergo an exhaustive analysis of their sonic influence prior to final selection.
Selected tubes
All tubes used are selected after 2 stage warm up. A fully computer monitored machine controls the process & at the end of this, selects the perfect tubes which are then matched for a perfect balance.
