Synthesis Action A50Taurus

Three models of stereo tube amplifiers with onboard DACs, 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 tubes in Ultra-Linear (UL) push/pull operation. The A50Taurus, like its bigger brother, also features a newly designed custom output transformer, resulting in a rich soundstage with an authority that belies its 50W. FEATURES USB & S/PDIF input For the first time, we include an onboard 24-bit 192kHz Wolfson DAC for an extraordinary listening experience. DC-powered tube heaters All tubes, except the KT88/6550, have DC-stabilized heater circuits to reduce hum to a near-inaudible minimum. Output transformer The output transformer uses high-grade iron-silicon for superb frequency reproduction & width. With this newly designed custom output transformer, unique to the A50Taurus, we are able to achieve 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 that perfectly matches the aesthetics of the "ACTION" series. Feet Four CNC-machined aluminum feet with natural rubber inserts. The depth & form of these rubber feet have been calculated to minimize vibrations of the amplifier, isolating it from its surroundings. Binding posts Gold-plated professional binding posts for a continuous oxidation-free connection further improve sound refinement. Sockets Gold-plated ceramic sockets for a continuous oxidation-free connection further improve sound refinement. Components The 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 a two-stage warm-up. A fully computer-monitored machine controls the process & at the end, selects the perfect tubes, which are then matched for a perfect balance.
