New model of stereo tube amplifiers with DAC's on board, guaranteeing exceptional sonic performance from any digital source. Made with the finest materials & advanced technology, this series is a sophisticated blend of research & experience. Designed without compromise far a rich sound & faithful music reproduction.
The A40Virtus provides a minimum of 40 watts per channel, power output from a pair of KT66's in Ultra-Linear (UL) - push/pull operation.
The A40Virtus features a newly designed custom output transformer resulting in a rich sound stage but with an authority that belies its 40Wpc.

FEATURES

- 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 stabilized heater circuits to reduce hum noise to a near in-audible minimum.

- Output transformer
The Output transformer uses a Hi-Grade iron-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 original 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 aluminum feet with an insert of natural rubber. The depth & form of these rubber feet has been calculated to minimize vibrations of the amplifier in isolation from its surroundings.

- Binding posts
Gold plated professional binding posts for a continued oxidization free connection further improve sound refinement.

- Sockets
Gold plated ceramic sockets for a continued oxidization 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.
