Crossfire Evo PA
Pure single-ended triode performance defined by organic musicality and transparency.
The Crossfire Evo PA represents the hallmark of Ayon Audio's single-ended triode development, drawing upon the proprietary AA62B-S power tubes to achieve unparalleled musical fidelity. As an uncompromising stereo power amplifier, it is designed for those who seek the direct, tactile connection to the music that only a high-current, DHT-based design can provide.
At the core of its architecture is a commitment to the shortest possible signal path. By employing a zero-negative-feedback circuit and avoiding all solid-state devices in the signal path, the amplifier preserves the raw harmonic structure of the signal. This purist philosophy ensures that the music unfolds with natural fluidity, maintaining the delicate balance between macro-dynamic impact and micro-dynamic nuance.
The sonic signature is defined by its stunning holography and a remarkably clean, grain-free backdrop. It reproduces the atmosphere of the original performance with clarity and resolution, offering a relaxed yet highly involving experience. With its redesigned EVO-generation power supply and custom wide-bandwidth transformers, the amplifier maintains authoritative control and stability, even when tasked with driving challenging loudspeaker loads.

Design & Philosophy
The Crossfire Evo PA is governed by the belief that circuit simplicity is the greatest asset in audio reproduction. By stripping away non-essential components and focusing on the directness of the single-ended triode design, Ayon ensures the amplifier acts as a transparent window. The dual-choke filtered power supply is central to this design, providing complete isolation between amplification stages and ensuring the high-speed energy delivery required for accurate transients.

Build & Materials
Every unit is hand-assembled in a high-grade, non-magnetic, brushed anodised aluminium chassis designed to suppress mechanical vibration. The construction incorporates custom beryllium-copper tube sockets, high-speed coupling capacitors, and point-to-point internal wiring to eliminate signal degradation. This meticulous attention to detail results in a masterpiece of craftsmanship built for decades of reliable service.

Listening Notes
Listeners can expect a holographic 3D soundstage that extends well beyond the speakers. The performance is characterised by a liquid, transparent midrange and a fast, punchy bass that defies traditional single-ended limitations. It is an extremely engaging amplifier that excels at revealing the atmosphere and subtle emotional cues of a recording, providing a fatigue-free and authentic musical experience.
