Synthesis Action A50Taurus

Three models 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 for a rich sound & faithful music reproduction.

The A50Taurus provides a minimum of 100 watts (50W per channel), power output from 4, KT88/6550's in Ultra-Linear (UL) - push/pull operation.

The A50Taurus like it's bigger brother also features a newly designed custom output transformer resulting in a rich sound stage but with an authority that belies its 50W.

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
All tubes, except KT88/6550, have DC stabilised 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 A50Taurus 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 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 A50Taurus 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.
