Ayon Auris II


Ayon AURIS II “Reference” preamp

For over 4 decades, Ayon Audio has been handcrafting world class vacuum tubes and vacuum tube audio equipment, setting the benchmark and new standards for high end audio performance. Altruistic reliability, product durability, Ayon Iconic design and superb resale value.

Since its market launch in 2014, astonishing consumers and professionals with a new benchmark of sonic precision and performance reliability, the Auris is hailed as a legend in its own time. The Ayon Audio Auris inspires the admiration and loyalty of Audiophiles worldwide. Styled to fit a new, modern design with unsurpassed audio quality. It is one of the rare tube preamps capable of offering the finest in recorded music with real/live tonal characteristics. Voiced to perfection, the Auris preamplifier is exceptional and spectacular in every detail. We have re-designed the output stage, power supply, phonostage (new phono re-design) and the quality of the components have been dialed-in to purity in key areas.

The low Output Impedance, purist parallel Single Ended 6H30 circuit topology, using zero dB negative feedback is an exclusive Ayon design. The Line Gain is user Switchable, 0dB or +6dB, therefore the Auris II preamplifier offers a very versatile coupling with any type of amplifier. Completely modular and upgradable for future enhancements. Options are: unbalanced or fully balanced/unbalanced, Signature version and Phono MM/MC-H, MC option for all your wants and needs. All existing Auris I version preamps can be retrofitted to the newest version II.

The Ayon Auris “Reference” preamp represents the industry benchmark in preamplifier design, based on 6H30 vacuum tube. Excellence in engineering, a special vacuum tube rectified power supply and superior premium components provide a special magic to the reproduction of music. The performance of the new Auris II is outstanding, very musical and neutral, transparent and vivid in its presentation. Music is reproduced with uncanny realism, with a holographic soundstage setting a new standard, previously unavailable at this price point.


Features & Design

Full-featured Pure Class A single ended & true balanced triode vacuum tube stereo preamplifier

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.

-Very short signal path
-Simplest direct circuit path for purest musical sound and high reliability
-Low output impedance to drive any tube or solid state power amp
-High current and low impedance design that operates the tubes in the perfect waveform
-Minimal discrete wiring for optimum signal propagation
-High quality parts throughout
-Selector switch engages relays located near the RCA jacks to switch all inputs

Vacuum 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 accurately damped and RFI/EMI ultra shielded
-Innovative power supply provides 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 preamplifier
-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 models is quite unique to the entire high end tube amplification industry. Such extensive topology provides for quieter backdrop for which the music can unfold in its entirety.

It further establishes the fast and controlled bass response and the full bodied expression of the mids and the highs. 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


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 is used and its location, that ranks our products apart from the masses.

Mechanical and Electrical Construction

The high grade elegant aluminum chassis plays an integral part producing a richer, more lustrous tonality with a cleaner background and less hash and grain.
