"Referens triode rörbestyckad DAC "


Ayon Audio presenterar med stor tillfredställelse den suveräna Skylla II DAC'en som erbjuder fullt balanserad digital och analog konstruktion. I den digitala domänen är fyra Burr-Brown PCM-170K ordnade i äkta differentiell mono konfiguration. Det differentiella steget är sammansatt av två 6H30 högströms rör per kanal. Skylla II DAC använder en enormt överdimensionerad, högkapacitets nätdel för det analoga 6H30 utgångssteget med "bryggad" rör-likriktning, choke koppling, tre överdimensionerade nättransformatorer, två för den analoga och en för den digitala delen.
Skyllas återgivning är rik och detaljerad, ytterst transparent och holografisk, och det resulterande ljudpanoramat presenterar en fullständigt realistisk återgivning av inspelningen, en livslevande spegelbild av original upptagningen. Skylla II tillhandahåller audiofilen en ny, hänförande nivå av digital uppspelnings upplevelse, endast jämförbart med de absolut bästa analoga källorna.

Features & Design


Full-featured Tube D/A converter with preamp function.
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.

  • Logical sequenced soft-start power up for extended tube life
  • 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
  • Separate analog output stage for left and right channel
  • Burr Brown D/A converter
  • Upsampling 24bit/192kHz and on/off switchable
  • Digital input
  • Analog input
  • USB input (24/96)
  • Digital output


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.

  • 3 separate R-Core / Low noise – insulated power transformer for digital & analog
  • Tube rectification
  • Dual 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 6H30
  • AC power line filter to avoid noise and hash from entering into the unit.
  • 10 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.

  • Selected, premium quality passive components used in all applications
  • High speed & high quality audiophile grade coupling capacitors
  • High quality Special tube sockets with gold pins
  • Superior capacitors ( MKP 1% )
  • High quality – RCA & XLR jack
  • Gold-plated industrial grade PCB


Mechanical Construction
The high grade aluminum chassis impart 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.

  • Front panel descriptions are engraved
  • AC phase polarity control indicator
  • The aluminium feet are resonance absorbing types
  • Metal remote commander
  • Chassis finish: black / chrome
