The Ayon Audio Spirit V Integrated inspires the admiration and loyalty of Audiophiles worldwide. Styled to fit a new, modern design with unsurpassed audio quality.

The Pure Class A Spirit V is a new generation of a fully balanced design, vacuum tube KT150 stereo integrated power amplifier, 70+70 Watts RMS, Pentode, Triode operation. It took years of development and refinement resulting in unique minimalist true balanced circuit topology to produce an accurate and seductive holographic soundstage. Musical finesse with fine details and powerful performance has been combined, without compromise, into one convenient chassis with affordable pricing. We are confident that the value and musical performance will again set a new musical experience in high end audio.

The new Spirit V is not simply updated version of the Spirit III; it is a totally new re-design, new system processing and protection circuit boards. All the gain and driver stages have been also re-designed and optimized, providing for the shortest signal path and direct signal flow. The new volume control is incredibly accurate, the new driver stage choke and the new output transformer has improved stability by 100%; as well as many other design modifications. The result is a flagship at an affordable price.  A fast tight bass, wide open three dimensional midrange, super smooth highs that do not roll off. The transparent, holographic soundstage are the strengths of this remarkable integrated amplifier.

For over 4 decades, Ayon Audio has been handcrafting world class vacuum tubes and vacuum tube audio equipment, setting the benchmark and new standards for high end audio performance. Altruistic reliability, product durability, Ayon Iconic design and superb resale value.

Vacuum Tubes

The choice of signal and power tubes have a significant influence on the sound and hence on the inspiration and joy of listening. This is not only the decision between good and bad tubes but finally the interaction of the different types of tubes and their combination that are used in the various Ayon amplifiers.

Signal Path

We believe that the simplest circuits work best together with the shortest signal path. The shorter the signal path is, the less possibility of sonic degradation from various sources, including the wire itself. Even on the circuit boards, the copper traces are kept to a very minimum length. The completely redesigned circuit board provides a more straightforward and direct approach to the signal paths.

Logical sequenced soft-start power up for extended tube life
Power tube and electronic protection circuit system
0dB negative feedback
Ultra short signal path
Simplest direct circuit path for purest musical sound and high reliability
No solid state devices in the signal path
High current and low impedance design that operates tubes in the best areas their curves
Minimal discrete wiring for optimum signal propagation
Automatic and manual bias adjustment
No followers or buffers in the signal path
High quality parts throughout
Selector switch engages relays located near RCA jacks to switch all inputs

Power Supply

The power supplies have been further refined with new components and enhanced AC line noise filtration. Separate power transformers, chokes and filters provide total isolation between the input and output stages which makes this a pure power source. We also use electrolytic capacitors with much larger storage capacity to make up for the loss in filtering when using resistors in lieu of inductors.

2 separate Low noise –insulated power transformers
Power transformers are encased, excellent damped and RFI/EMI shielded
Innovative power supply provides a high speed energy delivery on transients
Choke filtered power supply for driver stage and KT150 power amp section
Separate and isolated power supplies over each stage of amplification
High current filament-regulator for pre and driver tubes
Regulated DC filament supplies with soft start
AC power line filter to avoid noise and hash from entering into the unit.
High capacitance energy storage.
Current in-rush limiting
Auto sequencing – Power on cycle completes in 1 minute

Dual Grounding System

The modification of the grounding topology leads to increased rejection of noise from the power supply and other areas. The dual grounding topology used in all of our amplifiers is quite unique to the whole hi-end tube amplification industry. Such extensive topology provides for quieter backdrop for which the music can unfold in its entirety. It further establishes the quick and controlled bass response and the full-bodied expression of the high frequency. The ground leg of the signal has not been neglected and given meticulous attention in its implementation. The importance of proper grounding cannot be over emphasized.

Output Transformer

The super-wide bandwidth output transformer’s major strength is that it can deliver the current in the bass, while at the same time maintaining the speed in the high frequencies, dramatically improving the square wave response of the amplifier. The effect is a much more natural and relaxed sound with much better clarity, resolution and fluidity.

High efficiency with low insertion loss for optimal current and voltage transfer
Multiple tight layering and coupling for extended frequency response
Output transformers are sealed with an anti-resonance compound material


The type of parts used therefore must have a synergistic relationship to the circuit they are placed in. It is this relationship of which type of part to use where, that ranks our products apart from the mass.
