Elysian — where the queen of triodes meets the power of creation.

Trafomatic Audio proudly presents the Elysian Mono Power Amplifier, a true statement piece designed for the most demanding audiophiles and music lovers. Built around legendary triode tubes and the company’s renowned transformer expertise, Elysian represents a perfect union of classic vacuum tube heritage and modern engineering precision.

At the core of Elysian’s architecture are two GM70 triodes operating in a parallel single-ended Class A configuration. This powerful topology allows the amplifier to deliver exceptional authority and dynamic headroom while preserving the unmistakable purity and tonal richness that single-ended triode amplifiers are famous for. The result is a presentation that feels both powerful and effortless, capable of revealing the emotional depth and subtle nuance within every recording.

Driving the GM70 output stage is the legendary AD1 mesh plate triode, widely regarded among enthusiasts as the queen of directly heated triodes. Celebrated for its graceful sonic character and remarkable harmonic complexity, the AD1 plays a crucial role in shaping Elysian’s musical personality. Its delicate yet highly expressive nature ensures that even the smallest musical details are reproduced with stunning realism and natural flow.

In order to preserve signal purity and maintain perfect phase relationships, Trafomatic employs a transformer-coupled interstage design between the driver and output sections. This purist approach allows for extremely accurate energy transfer while eliminating the compromises often associated with capacitor-coupled stages. The result is greater tonal integrity, improved dynamics, and an overall sense of musical coherence.

At the input stage, the classic 6SN7 triode forms the foundation of the amplifier’s signal path. Revered for decades by audio designers, the 6SN7 is known for its musical transparency, tonal balance, and remarkable reliability. In Elysian, it provides the initial voltage amplification while establishing the amplifier’s natural sonic signature — one that balances refinement, warmth, and clarity.

Central to the performance of every Trafomatic amplifier are the company’s hand-wound output transformers, and Elysian is no exception. Carefully designed and meticulously crafted in-house, these transformers are optimized specifically for the GM70 output stage. Their precision construction ensures exceptional bandwidth, allowing the amplifier to reproduce deep bass with authority while maintaining delicate, extended high frequencies. More importantly, these transformers unlock the full harmonic richness and spatial depth contained within the music.

The listening experience delivered by Elysian is both powerful and immersive. Music flows with a sense of ease and naturalness, presenting instruments and voices with remarkable dimensionality. Large orchestral works expand effortlessly into the listening space, while intimate recordings reveal the subtle textures and emotional expressions of performers.

Every detail of the amplifier reflects Trafomatic Audio’s dedication to craftsmanship and sonic excellence. From the careful tube selection and circuit design to the precision-wound transformers and robust construction, each element has been thoughtfully implemented to serve a single purpose: to reproduce music with honesty, beauty, and emotional impact.

The Elysian Mono Power Amplifier is not simply an electronic component. It is a celebration of musical artistry and engineering mastery — where emotion, craftsmanship, and sound come together in perfect harmony.
