AYON NW-T Netwerk Transport met DSD

Ayon NW-T DSD Netwerk Transport
The AYON NW-T DSD is a new outstanding design which includes a Network-Transport with its “tube buffered digital output stage” and an Analog/Digital converter (ADC). The Network-Transport can be connected with any external DAC or CD-player with a digital input (DAC section). Furthermore its built-in ADC can be used to convert analog signals (e.g. of a phono-stage) into digital signals or into FLAC files respectively and to store them afterwards in an NAS. Special attention was paid to the tube-power supply and the digital output signal, because this digital interface is significantly involved to achieve "analog-magic" sound properties in the external DAC to a large extent. The NW-T was designed to maintain all advantages of a tube (in the power supply as well as in the digital output stage) in combination with streaming. The NW-T DSD uniquely unifies both and offers a new dimension of sound far above its class.
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. 

Network Player
  • User interface on QVGA 3.5” TFT display 
  • Internet radio (vTuner) 
  • UPnP streaming from PC via 100base-T Ethernet / 
  • Streaming audio from USB HS (mass storage device) 
  • WAV (lpcm) - up to 192khz/24bit 
  • FLAC - up to 192khz/24bit 
  • AIFF - up to 192khz/24bit 
  • AAC, HE-AAC (up to 24bit 96 kHz) , DSD
  • LPCM (up to 24bit 192 kHz on wired LAN and up to 24bit 96 kHz on wireless LAN) 
  • NetAPI with Ayon app for iPad, iPhone/iPod and Android 
  • Logical sequenced soft-start power up for extended tube life 
  • Warm up function 
  • Ultra short signal path 
  • Simplest direct circuit path for purest musical sound and high reliability 
  • Minimal discrete wiring for optimum signal propagation 
  • No DC servo that degrades the signal 
  • High quality parts throughout 
  • 6H14 tube (digital output - signal buffer) 
  • Upsampling 24bit/192kHz and on/off switchable 
  • Ethernet (RJ45) 
  • WIFI 
  • ADC input - S/PDIF (RCA), 24/192kHz 
  • 2 x USB type “A” inputs for Memory stick or USB drives 
  • Digital output - S/PDIF (RCA), AES/EBU (XLR), TosLink, BNC and I2S 
  • Digital volume control 
  • Separate Display for Network-Player and Volume/ ADC input 

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.
  • Dual R-Core / Low noise – insulated power transformers for digital & vacuum tube 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. 
  • Tube rectification for tube buffered digital output stage 
  • 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.
  • Selected, premium quality passive components used in all applications 
  • High speed & high quality audiophile grade capacitors 
  • High quality special tube sockets with gold pins 
  • High quality – RCA, BNC & XLR jack
