Spark V

Pure single-ended triode amplification featuring the renowned 6C33 vacuum tube.

The Spark V represents a significant evolution in Ayon Audio's pursuit of sonic transparency, serving as a dedicated single-ended triode integrated amplifier for serious music lovers. By meticulously rebuilding the power supply, pre-driver stage, and output transformers, this model achieves a level of performance that challenges much more costly designs while maintaining the soulful character of its 6C33 vacuum tube foundation. At the core of the design is a commitment to the simplest possible signal path. By eschewing all forms of negative feedback and removing solid-state devices from the signal chain, the amplifier preserves the raw emotional texture and transient speed of the source. The architecture avoids buffers and followers, ensuring that the music remains untainted and immediate. The sonic character of the Spark V is defined by its ability to render a wide, three-dimensional soundstage with remarkable clarity. It combines the warmth and midrange detail expected from high-quality triode amplification with a fast, controlled bass response that remains punchy and articulate. This is a refined, fatigue-free listening experience that balances technical precision with organic, natural fluidity.

Key Features

01

Zero-feedback circuit

The ultra-short signal path eliminates negative feedback to preserve transient speed and harmonic integrity.

02

6C33 power tubes

These tubes are chosen for their low plate impedance and high current capability, making them ideal for driving demanding loudspeaker loads.

03

Choke-filtered power supply

Separate transformers and chokes provide total isolation between stages, ensuring a pure, noise-free energy delivery.

04

Dual grounding topology

A unique switchable grounding system provides a quieter backdrop, allowing for greater resolution and a more controlled bass response.

05

Super-wide bandwidth transformers

Custom output transformers maintain speed in the high frequencies while delivering the current necessary for deep, accurate bass.

Design & Engineering

Chapter 01

Design & Engineering

The Spark V is built on the philosophy that circuit simplicity is the greatest asset in audio reproduction. By stripping away non-essential circuitry, Ayon Audio ensures the shortest possible signal path. This purist approach relies on high-quality components and proprietary wide-bandwidth transformers to manage the transition from the high-current demands of the bass to the delicate nuances of the upper registers.
Build & Construction

Chapter 02

Build & Construction

Housed in a high-grade brushed anodised aluminium chassis, the Spark V is designed to eliminate mechanical hash and grain. Every unit is hand-assembled with precision-machined control knobs and resonance-absorbing feet. The heavy-duty construction not only ensures long-term reliability but also provides a non-magnetic environment that protects the fragile internal signals from external interference.
Listening Notes

Chapter 03

Listening Notes

The Spark V brings a rare sense of scale to smaller-wattage systems, projecting a holographic 3D image that extends well beyond the speakers. It avoids the soft, overly romanticised sound of some tube amplifiers, opting instead for a fast, punchy delivery that is highly revealing of low-level detail. It is an amplifier that captures the atmosphere of a live performance with exceptional ease and authority.
