Ayon Audio CD-35 II CD Player

The Ayon CD-35 II establishes a new benchmark in SE-Triode vacuum-tube CD-Player performance by combining a fully balanced PCM-DSD DAC.
The CD-35 II is also prepared for computer/music server playback and DSD professional audio.  The CD-35 II is in many respects a new ground-breaking CD-Player design with an advanced technology with a new vacuum tube output stage, new magnetic integral clamp system, new DAC design and a switchable True PCM-DSD converter (DSP module).

Based on a zero-feedback design, pure tube circuit design and a tube rectified power supply, the CD-35 II reveals the manifold layers of music with utmost transparency while projecting a deep and highly focused 3D soundstage. The bass is tight and powerful, the midrange pure and liquid, natural, while extraordinarily clean and finely detailed, but not analytical.

The Reference CD-35 II Player/DAC offers an uncompromising quality level in every aspect.  The CD-35 II is one of the most exciting CD Players to date. The vacuum tube output stage is
remarkable and for sure the best sounding CD Player that Ayon Audio ever built.

Features

Pure 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, 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 highest reliability
• Low output impedance for driving long runs – interconnect to an amplifier, tube or solid
state power amplifier
• 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
• No DC servo that degrades the signal
• Highest quality parts throughout
• Fully hand assembled to insure the highest level of craftsmanship
• Separate analog output stage for left and right channel
• The volume is controlled 100% in the analogue domain
• DAC digital input – S/PDIF (RCA) , AES/EBU (XLR), I2S, BNC, USB, 3 x BNC for DSD;
• Digital output – S/PDIF (RCA)
• Ultra-low jitter internal clock generator

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
6H30/5687 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
• Innovative power supply provides a high speed energy delivery on transients
• Separate and isolated power supplies over each stage of amplification
• Tube rectification for 6H30/5687 analog output stage
• Choke filtering for 6H30/5687
• Regulated DC filament supplies with soft start for 6H30/5687
• 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 masses.

• 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
• 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 background
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.

• Backlit function buttons
• Modified suspension system to isolate the CD-transport from mechanical vibrations
• Anti-vibration magnetic integral CD-clamp/Lid system in dark acrylic
• Front panel descriptions are engraved
• The aluminum feet are resonance absorbing types
• Chassis finish: black / chrome
