“Reference triode tube DAC ”
Ayon Audio is pleased to introduce the superb Skylla II DAC featuring
a fully balanced digital and analog design. In its digital section,
four Burr-Brown PCM -1704K DACs are arrayed in a true differential dual
mono configuration. The differential gain stage is composed of two 6H30
high-current tubes per channel. The Skylla II DAC features a vastly
overrated, high capacity power supply for the 6H30 analog output stage
with tube “bridge” rectification, choke coupling, three oversized power
transformers, two for the analog and one for the digital section. The
Skylla`s sound is rich and detailed, highly transparent and holographic,
the resulting sound field representing an complete, realistic
reproduction of the recording, a life-like mirror-image of the original
performance. The Skylla II DAC provides audiophiles with a new, exalted
level of digital playback experience, comparable only to the best
available analog sources.

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
Components
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
