State of the art
The Spheris II - Phonostage is designed to be the new reference standard in vacuum-tube phonostage pre-amplification and for audiophiles who will accept nothing less than simply the best. It is a marvel of engineering with its unique tube circuit design and construction. This preamplifier sets a new standard for natural musical performance with its extraordinarily wide bandwidth, extremely low distortion, colourful, superior dynamic range and an airy three-dimensional holographic soundstage.
The external Spheris II AC~ Regenerator offers stable, regulated and purified AC power regardless of the incoming AC line quality. This power supply provides a lowered noise floor, more liquidity, better spatial three-dimensional imaging, greater focus, richer colours, and decreased glare & haze.
2 Chassis full-featured Class A − triode single-ended & balanced vacuum- tube stereo phonostage preamplifier
Unique new pure vacuum tube-circuit design with single gain stage and incorporates only one coupling capacitor at its output stage
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.
AC~ReGenerator - 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.
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 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.
