Quotation to the predecessor:
Heavy on the wire Stereoplay 2012 / 02 "Anyone who has heard of them understands that this tube is no longer an alternative principle" (Johannes Maier)




"One of the most superb sounding single-ended triode amplifier".

The Ayon Crossfire Evo is the little brother of our famous "Vulcan Evo" amplifier.
The new driver stage for the Crossfire Evo amplifier has been completely re-designed and is now operating on our own new AA20B driver tube as well as providing the shortest signal path and the most direct signal flow. This mono power amplifier offers absolutely breathtaking realism, utmost neutrality, great dynamics, astounding resolution and truly realistic bass performance from our acclaimed single-ended triode circuit.

High-end tube amplifier designs have quickly earned the reputation of a milestone among high-end tube amplifier designs.

Vacuum Tubes

The choice of signal and power tubes have a significant impact on the sound and on the inspiration and joy of listening. This is not only the difference between the different types of tubes and their combinations. Today only a few manufacturers produce pure tubes for pure audio amplification; One of them is Ayon Audio's outstanding single-ended triode power tubes (AA32B-S, AA52B-S and AA62B) based on the WE 300B.

Signal path

We believe that the simplest circuits work best with the shortest signal path. That's why our SE triode amplifiers have been used to deliver single-ended, pure class A circuitry. The shorter the signal path, 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
● Tube and electronic protection circuit system
● 0dB negative feedback (of any kind)
● Ultra short signal path
● Simplest direct circuit path for pure musical sound and high reliability
● No solid state devices in the signal path
● High current and low impedance design in the best areas of their curves
● Minimal discrete wiring for optimum signal propagation
● No followers or buffers in the signal path
● High quality parts throughout
● Selector switch relays located near RCA jacks to switch all inputs

Power Supply

Single ended amps are more susceptible to power supply aberrations than push-pull amplifiers. The power supplies have been 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 it a pure power source and is a critical attribute for a single-ended amplifier. So using 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 high-speed energy delivery on transients
● Special choke filtered power supply for Ayon AA62B / AA82B
● Dual choke for pre and driver stage
● Tube regulated power supply (5U4G)
● Separate and isolated power supplies over each stage of amplification
● Separate high current filament regulators 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 capacity 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. Search 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 can not 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 lot 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
