Ayon Stealth XS


Many of our clients have in the past asked for a cheaper DAC based on the well-known Stealth or Stratos, which are built uncompromisingly and are among the best-sounding tube DACs. The Stealth “XS” version is the answer and offers many design highlights from its bigger brother, the Stealth. One of the major changes at the Stealth “XS” are the power supply system and the tube output stage. We did it very carefully and the Stealth “XS” version offer maximum flexibility and a super sound performance regardless of the price class that you would expect from an Ayon product with. A new vacuum tube-based DAC star was born and offers an outstanding price/performance and value.

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.

Warm up function
0dB negative feedback (of any kind )
Ultra short signal path
Simplest direct circuit path for purest musical sound and high reliability
Low output impedance for driving long runs interconnect to an amplifier, and any tube or solid state power amp
No solid state devices in the analog tube output (signal path )
Minimal discrete wiring for optimum signal propagation
No followers or buffers in the signal path
High quality parts throughout
Fully hand assembled to insure the highest level of craftsmanship

All digital inputs
Internal hardware PCM upsampler for CD sources to 24/192K (can be disabled)
Native 192kHz PCM and DSDx128 conversion
Ultra-low jitter internal clock generator
USB input (24/192 asynchronous and DSD)
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.

2 separate R-Core / Low noise – insulated power transformer for digital & analog
Tube rectification
Choke – filtered power supply and coupled with special film caps
Innovative power supply provides a high speed energy delivery on transients
Separate and isolated power supplies over each stage of amplification
Regulated DC filament supplies with soft start for tube
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.
