Ayon Audio Nätverkstransport

Den nya NW-T musik-streamern är en ny enastående konstruktion som inkluderar en nätverks-transport med "rör buffrade digitala utgångssteg" och en Analog/Digital konverter (ADC). Nätverkstransporten kan anslutas till vilken som helst DAC eller CD-spelare via en digital ingång (DAC sektion). Dessutom har den som sagt en inbyggd ADC (Analog till Digital Konverter) som kan användas för att konvertera analoga signaler (ex. phono- steg eller annan analog källa) till digitala signaler eller till FLAC filer respektive för att spara dem på en NAS.

 

Speciell uppmärksamhet har lagts på den rör bestyckade nätdelen och den digitala utsignalen, eftersom detta digitala "interface" (gränssnitt) är signifikant involverad då det gäller att åstadkomma "analog Magi" ljudåtergivning från den externa DAC'en i mycket stor utsträckning. NW-T konstruerades för att utnyttja alla fördelar från rören (i nätdelen såväl som det digitala utgångssteget) i kombination med streaming. NV-T unifierar unikt båda dessa och erbjuder en ny dimension av ljudkvalitet i sin klass.

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.

 

Network Player

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

 

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.
