Ayon AURIS “Reference” Preamplifier

After the success of the “smaller” Ayon preamplifiers many customers approached us wishing a modular and upgradeable concept. The new Auris is such a modular tube pre-amp design and is offered in some varieties: unbalanced or fully balanced, signature version and Phono MC/MM option for all varieties.

This “Reference” preamp represents the highest standard of preamp based on 6H30 design achievement and offers a holographic soundstage previously unavailable at this price class. The performance of the Auris is outstanding, transparent and vivid in its presentation. There is a huge space of the recording environment reproduced with uncanny realism. The purist 6H30 circuit topology is using zero dB negative feedback, no buffers and no followers or op amps are used anywhere in the signal path. Excellence in engineering, a special tube rectified power supply and super premium components selection provides a special magic to the reproduction of music.

Features & Design

Full-featured class A single-ended & true balanced triode vacuum tube stereo preamplifier
Pure vacuum tube-circuit design with single gain stage and incorporates only one coupling capacitor at its output stage

Vacuum Tubes
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.

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.

  • Vacuum tube current source loading for signal gain stage
  • Very short signal path
  • Simplest direct circuit path for purest musical sound and high reliability
  • Very low output impedance to drive any tube or solid state power amp
  • 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
  • No followers or buffers in the signal path
  • High quality parts throughout
  • 0dB negative feedback  (of any kind )
  • Selector switch engages relays located near RCA jacks to switch all inputs

Tube – Power Supply
The power supplies have been further refined with new components and enhanced AC line noise filtration. Low noise power transformer, 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.

  • Tube rectified power supply
  • Superior noise reduction
  • Low noise –insulated power transformers
  • Power transformers are excellent damped and RFI/EMI ultra-shielded
  • Innovative power supply provides a high speed energy delivery on transients
  • Dual choke filtered power supply for 6H30 tubes
  • Separate and isolated power supplies over each stage of amplification
  • Regulated DC filament supplies with soft-start power up for extended tube life
  • AC power line filter to avoid noise and hash from entering into the unit.
  • High capacitance energy storage.

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.

  • Central one-point star earth grounding
  • Dual grounding system

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.

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.

  • High selected, best quality passive components used in all applications
  • High speed  & high quality audiophile grade coupling capacitors
  • Special tube sockets with beryllium- copper spring pins
  • High quality – RCA input jack
  • Neutrik/Swiss – XLR chassis connectors
  • Special isolated – internal wiring
  • Gold-plated industrial grade PCB
  • High quality – Input selector switches
  • Volume control – 4 channel
