Ayon Orion II

"The entrance into high-end tube amplification".

The Orion II represents a dramatic rethinking of vacuum tube based
integrated amplifier industrial design while retaining the basic architecture
as our highly regarded "Spirit" amplifier.

The Orion II integrated amplifier combines neutrality, realistic dynamics and
power projection, true musicality with high resolution. Perfect finish, elegant discrete design and outstanding sonic performance make the "Orion II" unique, setting a new price-to-value standard in its class.

Vacuum Tubes
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.

Signal Path
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.

  • Logical sequenced soft-start power up for extended tube life
  • Power tube and electronic protection circuit system
  • 0dB negative feedback (of any kind) 
  • Ultra short signal path
  • Simplest direct circuit path for purest musical sound and high reliability
  • No solid state devices in the signal path
  • High current and low impedance design that operates tubes in the best areas their curves
  • Minimal discrete wiring for optimum signal propagation
  • Automatic and manual bias adjustment
  • No followers or buffers in the signal path
  • High quality parts throughout
  • Selector switch engages relays located near RCA jacks to switch all inputs

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.

  • Low noise –insulated power transformers
  • Power transformer is encased, excellent damped and RFI/EMI shielded
  • Innovative power supply provides a high speed energy delivery on transients
  • Choke filtered power supply
  • Separate and isolated power supplies over each stage of amplification
  • High current filament-regulator 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. 
  • Current in-rush limiting
  • Auto sequencing - Power on cycle completes in 1 minute

Components
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.

  • Selected,  quality passive components used in all applications    
  • High speed  & high quality audiophile grade coupling capacitors
  • Teflon tube sockets with beryllium- copper spring pins, custom made by Ayon
  • High quality – binding posts
  • High quality – RCA input jack
  • Teflon isolated - internal wiring
  • Copper matrix - internal signal cable
  • Gold-plated industrial grade PCB
  • All wiring to the circuit boards is done with the use of special pluggable pin-connectors. This is done for ease of repair should ever the need arise.

Mechanical Construction
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.

  • Improved heat ventilation chassis
  • Custom-made machined control knobs
  • The aluminium feet are resonance absorbing types
  • Engraved “ayon” logo
  • All front & rear panel descriptions are engraved
  • 4 line inputs & 1 direct input  & 1 USB
  • AC phase polarity control indicator
  • Volume & Mute function - RC
  • Metal remote commander
  • Chassis finish: black
