According to Spheris III Tube Preamp Linestage
The Ayon Audio SPHERIS III – Linestage has been designed to be the new reference standard in vacuum tube pre-amplification, and for audiophiles who accept nothing less than the best. It is an engineering marvel with its unique C3m tube circuit design, new revolutionary volume control system and construction. This preamp sets a new standard for natural musical performance with its extraordinarily wide bandwidth, extremely low distortion, colorful, superior dynamic range and an airy three-dimensional holographic soundstage.
The external Spheris III AC~ Regenerator provides stable, regulated, and sanitized AC power, regardless of the quality of the incoming AC line. This power supply provides a lowered noise floor, more liquidity, better spatial three-dimensional imaging, more focus, richer colors and NO glare and fog.
Features and design
2 Chassis Full Class A – Triode/Pentode Single Ended & True Balanced Vacuum Tube Stereo Preamplifier
Unique new pure vacuum tube circuit design with single gain stage and contains only one coupling capacitor at the output stage
The choice of signal and power tubes has a major influence on the sound and thus on the inspiration and listening pleasure. This is not only the decision between good and bad tubes, but also the interaction of the different types of tubes and their combination used in the different Ayon amps.
- Special tubes for stereo line amplification (tube life min. 10000 hours)
According to Audio SPHERIS III Signaalpad
We believe that the simplest circuits work best with the shortest signal path. The shorter the signal path, the less chance of noise degradation from various sources, including the wire itself. Even on the printed circuit boards, the copper traces are kept to a very minimal length. The completely redesigned circuit board provides a more straight-lined and direct approach to the signal paths.
According to Audio SPHERIS III
*Ultra short signal path
*The simplest direct circuit path for the purest musical sound and high reliability
*Very low output impedance to drive any tube or solid state power amplifier
*No solid state devices in the signal path
*High current and low impedance design that drives tubes in their curves in the best areas
*Minimum discrete wiring for optimal signal dispersion
*No followers or buffers in the signal path
*High-quality parts throughout
*0dB negative feedback (of any kind)
*All line inputs – impedance > 1MOhm
*Selector switch turns on relays is located near RCA jacks to switch all inputs
*Special alloy solder used for the best electrical connection
AC~ReGenerator – Power supply
The power supplies have been further refined with new components and improved AC line noise filtration. Separate current transformers, chokes and filters provide total isolation between the input and output stages, making this a pure power source. We also use electrolytic capacitors with a much larger storage capacity to compensate for the loss of filtering when using resistors instead of inductors.
* Tube rectified power supply with built-in AC ~ Regenerator
* Low distortion regenerated AC and sine wave
* Superior noise suppression
* 2 separate low noise isolated power transformers
* Power transformers are encapsulated, highly damped and RFI/EMI ultra-shielded
* Innovative power supply provides fast energy delivery during transients
*Triple choke filtered power supply for power tubes
*Separate and isolated power supplies across each gain stage
*Regulated DC filament power supplies with soft-start power-up for extended tube life
*AC power line filter to prevent noise and hash from entering the device.
* High capacity energy storage.
Double earthing system
The change in ground topology results in greater noise rejection from the power supply and other areas. The dual ground topology used in all of our amps is quite unique to the entire hi-end tube amp industry. Such an extensive topology creates a calmer backdrop from which the music can unfold in its entirety. It also provides the fast and controlled bass response and the full expression of the high frequency. The ground leg of the signal has not been neglected and much attention has been paid to its implementation. The importance of proper grounding cannot be overemphasized.
*Central one-point star earth
*Dual earth system (switchable)
The type of parts used must therefore have a synergistic relationship with the circuit in which they are placed. It is this relationship of what type of part to use where that sets our products apart from the crowd.
