Ayon Audio Orbis













€8500

Full-featured class A single-ended & true balanced triode vacuum tube stereo preamplifier
Pure vacuum tube-circuit design with single gain stage and incorporates only one coupling capacitor at its output stage

Vacuum Tubes
The choice of signal and power tubes have a significant influence on the sound and hence on the inspiration and joy of listening. This is not only the decision between good and bad tubes but finally the interaction of the different types of tubes and their combination that are used in the various Ayon amplifiers.

Signal Path 
We believe that the simplest circuits work best together with the shortest signal path. 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.
  • Vacuum tube current source loading for signal gain stage
  • Very short signal path
  • Simplest direct circuit path for purest musical sound and high reliability
  • Very low output impedance to drive any tube or solid state power amp
  • No solid state devices in the signal path
  • High current and low impedance design that operates tubes in the best areas their curves
  • Minimal discrete wiring for optimum signal propagation
  • No followers or buffers in the signal path
  • High quality parts throughout
  • 0dB negative feedback  (of any kind )
  • All line inputs - impedance > 1MOhm
  • Selector switch engages relays located near RCA jacks to switch all inputs
