We are proud to announce the introduction of the new Epsilon Evo. The new Epsilon Evo is a totally new design featuring new operating and protection circuit boards. All the gain and driver stages and its “ground system” have been also re-designed and optimized as well to provide for the shortest signal path and the most direct signal flow. We have also implemented a new choke system and an updated bias system. For the output transformer we have endeavored new ways with a first-time groundbreaking coil technology to achieve even more sound performance, by means of which the amplifier in the lower frequency range can work significantly more stable without limiting its fresh, vivid, and holographic sound performance. The added result of the new output transformer is a significant advance in sonic performance, wider and deeper airy soundstage with greatly improved deeper bass, punch and dynamics. It has also a wonderful ability to unravel complex musical threads with grain less purity and surprising musical dynamics in every volume level. All these technical measures and further developments lead to an Epsilon Evo revealing a new chapter of combination in sound and power, therefor outing itself as one of the best if not actually the outstanding mono block with 6 KT150 tubes per channel, independent of its price.
Full-featured true balanced vacuum tube mono power amplifier Switchable between pentode and triode mode Ideal also 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 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.
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.
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.
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.
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.
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.
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.
