Ayon Spirit V Integrated & Power Amplifier

Ayon Spirit V & High Fidelity Award

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!

NO Ultra-Linear/Triode Operation – You do not want this mode of operation in your Tube Amp!

Pure Class A – After nine years of manufacturing of the legendary Spirit III model we are proud to announce the introduction of the new Spirit V. The new Spirit V is not a simple update; it is a totally new re-design featuring new operating and protection circuit boards.All the gain and driver stages have been also re-designed and optimized as well to provide for the shortest signal path and the most direct signal flow. A newly installed volume control as well as a new driver stage choke and a new output transformer as well as many minor modifications complete the comprehensive redesign of the new Spirit V.It’s fast, airy, dynamic, punchy and deep bass performance, transparent and holographic soundstage is the strengths of this amplifier.

The Spirit V set a new standard in built quality, sound performance and its time-less design appearance,a new milestone it its price class.

The Spirit V integrated is also available as a pure stereo power amp, the Spirit PA!

Features & Design

Full-featured pure class-A tube stereo integrated amp or pure power amplifier
Switchable between pentode and triode mode
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
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.

Power transformers are encased, excellent damped and RFI/EMI shielded
Innovative power supply provides a high speed energy delivery on transients

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.

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.
