Spirit V

Pure class A triode performance in a versatile push-pull design.

The Ayon Audio Spirit V stands as a definitive reference in the integrated amplifier category, representing the culmination of years of refinement in push-pull vacuum tube design. Built upon the legacy of its predecessors, this model features a total re-engineering of the power supply and output stages to provide a level of sonic transparency and dynamic authority that remains rare in its class. At its foundation, the amplifier utilizes a zero-negative-feedback circuit to maintain the integrity of the original signal. By stripping away non-essential solid-state devices and utilizing custom-wound, super-wide bandwidth output transformers, the Spirit V ensures that every micro-dynamic nuance is preserved. The result is a sound that is both fast and emotionally resonant, avoiding the common pitfalls of typical tube-based amplification. Whether running in triode mode for intimate, holographic realism or pentode mode for visceral dynamic impact, the Spirit V presents music with an expansive soundstage and striking clarity. It is a confident, restrained performer that balances rich, full-bodied textures with a tight, authoritative bass response, offering a fatigue-free experience that invites long-term engagement with any high-end audio collection.

Key Features

01

Switchable triode/pentode modes

Allows for immediate toggling between the smooth, natural textures of triode operation and the high-power, dynamic grip of pentode mode.

02

Zero negative feedback

The signal path is kept entirely direct, ensuring superior transient speed and the preservation of low-level harmonic information.

03

Dual grounding system

A sophisticated switchable grounding topology reduces background noise and improves resolution, providing a silent backdrop for the music.

04

Super-wide bandwidth output transformers

Custom-engineered for extended frequency response and low insertion loss, these transformers maintain speed and authority even during complex musical passages.

05

KT150/KT170 compatibility

Optimized for modern power tubes to deliver high current capability and stability when driving difficult loudspeaker loads.

Engineering Philosophy

Chapter 01

Engineering Philosophy

The design of the Spirit V is governed by the principle of simplicity. By keeping the signal path as short as possible and using no negative feedback, Ayon Audio ensures the amplifier behaves with complete honesty toward the source material. Each component, from the copper matrix wiring to the custom beryllium-copper tube sockets, is chosen to minimize degradation and maximize reliability.
Build and Craftsmanship

Chapter 02

Build and Craftsmanship

Each Spirit V is hand-assembled in a high-grade, brushed anodized aluminum chassis, which serves to isolate the delicate circuitry from mechanical vibration and RFI/EMI interference. Features such as the backlit logo, engraved paneling, and an integrated analog bias meter demonstrate a dedication to both functional elegance and the timeless aesthetic associated with Ayon Audio.
Listening Notes

Chapter 03

Listening Notes

The Spirit V is noted for its ability to project a massive, holographic soundstage that places every instrument with pinpoint accuracy. The performance is characterized by a natural, saturated tonality that brings a tactile sense of presence to recordings. Its bass control is exceptionally tight for a tube amplifier, providing a visceral impact that remains controlled and articulate even in complex orchestral pieces.
