A40 VIRTUS Integrated




A40Virtus   40W Integrated Stereo Amplifier

New model of stereo tube amplifiers with DAC's on board, guaranteeing exceptional sonic performance from any digitai 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.


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.

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.

Gold plated ceramic sockets for a continued oxidisation free connection further improve sound refinement.

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.
