Ayon audio Auris II - Unbalanced
Full-featured class A single-ended & true balanced triode vacuum tube stereo preamplifier
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.

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.
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.
Mechanical and Electrical Construction
The high-grade aluminium 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 is fully hand assembled to insure the highest level of craftsmanship.
The optional Phono Amplifier contains the best possible Parts available on the Market today. It has a Gain of 45 dB for MM or MC-H Cartridges and 65 dB Gain for low Output MC Cartridges. The Input Load is fixed 47 K for MM-MCH. Remote selectable Load 100 Ohm, 470 Ohm and 1 K for MC.
