The Synthesis A40 Virtus Integrated Stereo Tube Amplifier represents a significant advancement in sound technology, combining state-of-the-art digital capabilities with traditional tube amplifier warmth. This new model is specifically designed to elevate your listening experience by providing exceptional sound quality from any digital source. Constructed with the finest materials and cutting-edge technology, the A40 Virtus is a product of extensive research and experience, aimed at delivering uncompromised sound fidelity and rich, authentic music reproduction.

One of the key features of the A40 Virtus is its power output, which guarantees a minimum of 40 watts per channel. This robust performance is achieved through the use of a pair of KT66 tubes in Ultra-Linear (UL) push/pull operation. This configuration not only ensures a powerful output but also contributes to the amplifier’s ability to produce a rich and expansive sound stage. The authority and depth of the sound delivered by the A40 Virtus belie its 40 W per channel rating, making it an outstanding choice for discerning listeners.

The amplifier incorporates a newly designed custom output transformer, which plays a crucial role in its ability to produce high-quality sound. Made with Hi-Grade Iron-Silicon, this transformer is key to the A40 Virtus’s superb frequency reproduction and width. The meticulous design of this transformer allows for delicate and precise sound reproduction, staying faithful to the original recording. This feature underscores the commitment to achieving a sound that is as close to the original performance as possible.

Digital compatibility is a standout feature of the A40 Virtus, with the inclusion of a USB and S/PDIF input. For the first time, an onboard 24 bit 192 kHz Wolfson DAC is integrated, offering an extraordinary listening experience. This digital-to-analog converter ensures that digital sources are rendered with exceptional clarity and detail, enhancing the overall sonic performance of the amplifier.

The A40 Virtus also boasts a DC powered tube heater, where all tubes, except the KT66, have DC stabilized heater circuits. This innovation significantly reduces hum noise to a near inaudible minimum, ensuring a cleaner and more precise sound output. This attention to detail in minimizing interference and noise is indicative of the amplifier’s high-quality design and engineering.

Physical construction is another area where the A40 Virtus excels. The power supply and output transformers are secured in an extremely rigid “H” structure, which effectively isolates the unit from unwanted vibrations. This design choice helps in reducing noise to the tubes, further refining the sound quality. Additionally, the amplifier features four CNC machined aluminum feet with natural rubber inserts, specifically designed to minimize vibrations and isolate the amplifier from its surroundings.

The aesthetic design of the A40 Virtus is equally impressive. It comes with a remote control featuring a CNC machined case and soft button design, perfectly complementing the “ACTION” series’ aesthetics. The amplifier is also equipped with gold-plated professional binding posts and gold-plated ceramic sockets, ensuring an oxidation-free connection and further enhancing sound refinement.

Carefully selected components are at the heart of the A40 Virtus’s performance. Each component undergoes an exhaustive analysis to determine its sonic influence before being selected. This rigorous process ensures that only the best components are used. Moreover, all tubes are meticulously selected after a two-stage warm-up process. A fully computer-monitored machine controls this process, selecting the perfect tubes which are then matched for optimal balance.

The Synthesis A40 Virtus Integrated Stereo Tube Amplifier is a remarkable blend of advanced digital technology and traditional tube amplifier warmth. Its design and construction are a testament to the commitment to delivering high-quality sound. The meticulous attention to detail in every aspect, from the custom output transformer to the choice of components and tubes, ensures an unparalleled listening experience.
