Ayon Audio S-10 II

Ayon Audio S-10 II Signature – Roon Partner

The only vacuum tube based streamer on the market!

The Benchmark in streaming music! Pre-amplifier or not, 100% analog volume control.

Ayon S-10 II right

After three very successful years we have technically redesigned the S-10 to a great extent by refining and expanding the modular concept design. Based on this modular platform, the new S-10 II can be configured individually in different versions, depending upon the request and the requirements. The S-10 II includes a Music network player, computer playback, USB drive playback, analogue preamp with a quadrable analogue volume control system, a new dual mono Digital to Analog converter, an updated PCM – DSD converter converting all PCM-signals to DSD. Additionally, a separate self-sufficient server unit with variable hard-disk capacity can be installed. Furthermore, we have implemented a completely new streamer platform that can be equipped with a second self-sufficient streamer module for the server option. Of course, for Ayon the best possible reproduction has top priority. The Ayon S-10II produces a spacious 3D sonic performance, a wall to wall three dimensional soundstage. The Ayon S-10II makes your speakers disappear, an exceptional front end.

This tube-based network player offers the outstanding performance you would expect from an ayon product, setting a new sound performance standard in its price range.

Existing S-10 devices can be upgraded to the new S-10 MkII version.

Features & Design

Full-featured Network Music Player
Class-A triode vacuum-tube output stage for single-ended & fully balanced operation

Signal Path
We believe that the simplest circuits work best together with the shortest signal path. That is why our pre-amplifiers to date have used single-ended pure class-A circuitry. 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.

Power Supply

The power supplies have been further refined with new components and enhanced AC line noise filtration. Separate power transformer windings and filters provide total isolation between the input and output stage which makes this a pure power source and it is a critical attribute for a 6H30 output stage. 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.

*R-Core / Low noise – insulated power transformer for digital & analog
*Innovative power supply provides a high speed energy delivery on transients
*Separate and isolated power supplies over each stage of amplification
*AC power line filter to avoid noise and hash from entering into the unit.
*8 separate voltage regulators


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.
