Features & Design
Full-featured single-ended tube stereo integrated amp or pure power amplifier SE – pure Class-A triode vacuum tube-circuit design AA62B. Power output tubes high peak current & high voltage delivery. It is also ideal for more difficult loudspeaker loads.
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 difference between good and bad tubes, but also 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 and AA62B) based on the WE 300B.
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.
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 noise reduction 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 in 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.
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. This dramatically improves the square wave response of the amplifier. The effect is a much more natural and relaxed sound with much better clarity, resolution and fluidity.
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.
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.
