Ayon S-3 XS


Ayon S-3 XS Vacuum Tube Streamer Tube Network Player – Volume Control

Quality, Performance, Brand Name Recognition, Superb Soundstage!

Many of our clients have asked in the past for a more affordable Network-Player based on the famous S-3. The downgraded S-3 XS version is the answer and offers many design highlights from its bigger brother, the S-3.

Some of the major changes in the S-3 XS, are the power supply system and the tube output stage.

We did the downgrading very carefully in the S-3 XS version. It offers maximum flexibility and excellent sound performance in its price class. (Something you would expect from an Ayon product.)



Features & Design

Full-featured Network Music Player/DAC/Preamp
Class-A triode vacuum-tube output stage for single-ended & 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.  This makes it a pure power source which is a critical attribute for a 6922 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.

● Dual R-Core / Low noise – insulated power transformers for digital & analog separated
● 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.
● Dual tube rectification for 6922 analog output stage
● Choke
● 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 sets our products apart from the masses.

● Selected, premium quality passive components used in all applications
● High speed & high quality coupling capacitors
● High quality special tube sockets with gold pins
● Capacitors ( MKP)
● High quality – RCA & XLR jack
● Gold-plated industrial grade PCB

Mechanical Construction

The high grade aluminum chassis imparts a richer, more lustrous tonality with a cleaner back-ground 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.

● AC phase polarity control indicator
● The aluminium feet are resonance absorbing types
● Metal remote commander
● Chassis finish: black / chrome
