Ayon Audio Vulcan Evo Power Amplifier

“One of the most superb sounding and powerful single-ended triode amplifier”.

The new driver stage for the Vulcan Evo amplifier has been completely new re-designed and is operating now by our own new AA20B driver tube as well to provide for the shortest signal path and the most direct signal flow. This mono power amplifier offers terrific breathtaking realism, utmost neutrality, explosive dynamics, astounding resolution and truly realistic bass performance from our acclaimed single-ended triode circuit.

The result of a tour de force in the pursuit of sonic realism combined with our leading design expertise in single-ended triodes and advanced technological solutions has quickly earned the reputation of a milestone amongst high-end tube amplifier designs.

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. Today only few manufacturers still produce tubes for pure audio amplification; one of them is Ayon Audio with its outstanding single-ended triode power tubes (AA32B-S, AA52B-S, AA62B  and AA82B) based on the WE 300B.

Signal Path

We believe that the simplest circuits work best together with the shortest signal path. That is why our SE-Triode amplifiers to date have used single-ended pure class A circuitry. 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.

Power Supply

Single ended amps are more susceptible to power supply aberrations than push-pull amplifiers. 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 stage which makes this a pure power source and it is a critical attribute for a single-ended amplifier. 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.

Dual Grounding System

The modification of the grounding topology leads to increased reduction 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 has been 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.

Components

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 sets our products apart from the masses.

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.
