Ayon Spirit V



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.

Since the very first Ayon Spirit market launch in 2008, the New Ayon Spirit V is astonishing consumers and professionals with a new benchmark of sonic precision and performance reliability. 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.

The Spirit V is elegant, superb craftsmanship with a timeless appearance. Truly a new milestone!

The Spirit V Integrated is also available as a pure stereo power amp, the Spirit V P/A.

Features & Design

KT150 power output tubes Ideal also for more difficult loudspeaker loads



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  (of any kind )
  • 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.

  • Low noise –insulated power transformers
  • Power transformer is encased, excellent damped and RFI/EMI shielded
  • Innovative power supply provides a high speed energy delivery on transients
  • Choke filtered power supply
  • 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.


  • Ground switch
  • Central one-point star earth grounding
  • Dual grounding system (switchable)

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.

  • Super-wide bandwidth high performance output transformer
  • 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.

  • Selected, premium quality passive components used in all applications
  • High speed  & high quality audiophile grade coupling capacitors
  • Special tube sockets with beryllium- copper spring pins, custom made by Ayon
  • WBT NextGen – binding posts
  • High quality – RCA input jack
  • Neutrik/Swiss - XLR chassis connectors
  • Special isolated - internal wiring
  • Silver-copper matrix - internal signal cable
  • Gold-plated industrial grade PCB

Mechanical Construction

The high grade aluminum chassis impart a richer, more lustrous tonality with a cleaner background and less hash and grain. All brushed anodized anti-vibration-resonance and non-magnetic chassis’s are fully hand assembled to insure the highest level of craftsmanship.

  • Improved heat ventilation chassis
  • Custom-made machined control knobs

No, we do not use ultra-linear/triode operation – Inferior for High End Audio

Ultra-linear electronic circuits are those used to couple a tetrode/triode or pentode vacuum-tube to a load (e.g. to a loudspeaker).

‘Ultra-linear’ is also know as ‘distributed loading’; a circuit technique patented by Alan Blumlein in 1937. Ultra-Linear “distributed loading” was intended for guitar amps, etc.

• In pentode or triode, in which the screen-grid is connected to a stable DC voltage so there are no signal variations on the screen-grid (i.e. the screen-grid has 0% of the plate’s output signal impressed on it), or

• In triode, in which the screen-grid is connected to the plate (i.e. the screen-grid has 100% of the plate’s output signal voltage impressed on it), or

• a blend of triode and pentode, in which the screen-grid has a percentage (between 0% and 100%) of the plate’s output signal impressed on it. This is the basis of the Ultra-Linear “distributed load circuit” and is seen as a form of feedback, which alters the behavior of the electron stream passing from cathode to anode.

Ultra-linear/Triode introduces negative feedback, which squashes and compresses the sonic performance.

So the Pentode/Triode operation will yield a vastly superior response and more of a “tactile” or SET sound, more of a three dimensional sonic signature. Quite Superior!
