NEW Telefunken (Engraved Base) tube assembly, very rarely good for 10000e hours ...

Features & Design

2 Chassis full-featured Class A - triode / pentode single-ended & true balanced vacuum tube stereo preamplifier
Unique new pure vacuum tube-circuit design with single gain stage and incorporates only one coupling capacitor at its output stage
Limited production

Vacuum TubesThe choice of signal and power tubes have a significant impact on the sound and on the inspiration and joy of listening. This is not only the difference between the different types of tubes and their combinations.

    • Special tubes for stereo line amplification (tube life min 10000 hrs)

Signal path
The shorter the signal path is, the less the 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.

    • Ultra short signal path
    • Simplest direct circuit path for pure 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 in the best areas of 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
    • Special alloy solder used for the best electrical connection

AC ~ ReGenerator - Power Supply
The power supplies have been refined with new components and enhanced AC line noise filtration. Separate power transformers, chokes and filters provide total isolation between the input and output stages which makes this a pure power source. So using electrolytic capacitors with much larger storage capacity to make up for the loss in filtering when using resistors in lieu of inductors.

    • Tube rectified power supply with built in AC ~ regenerator
    • Regenerated AC power and low sine wave
    • Superior noise reduction
    • 2 separate low noise-insulated power transformers
    • Power transformers are encased, excellently damped and RFI / EMI ultra-shielded
    • Innovative power supply provides high-speed energy delivery on transients
    • Triple choke filtered power supply for power tubes
    • Separate and isolated power supplies over each stage of amplification
    • Regulated DC filament supplies with soft-start power up for extended tube life
    • AC power line filter to avoid noise and hash from entering into the unit.
    • High capacity energy storage.
    • Frequency meter (60Hz)

Dual Grounding System
The modification of the grounding topology leads to increased rejection of noise from the power supply and other areas.

The dual grounding topology used in all of our amplifiers is quite unique to the whole hi-end tube amplification industry. Search extensive topology provides for quieter backdrop for which the music can unfold in its entirety.

It further establishes the quick and controlled bass response and the full bodied expression of the high frequency.

The ground leg of the signal has not been neglected and given meticulous attention in its implementation. The importance of proper grounding can not be over emphasized.

    • Ground switch
    • Central one-point star earth grounding
    • Dual grounding system (switchable)

It is placed in a relationship with the group of companies that they are located in.

    • Ultra selected, absolute best quality passive components used in all applications
    • High speed & high quality audiophile grade coupling capacitors
    • Special tube sockets with beryllium- copper spring pins, custom made by Ayon
    • WBT / High quality - RCA input jack
    • Neutrik / Swiss - XLR chassis connectors
    • Special isolated - internal wiring
    • Premium internal signal cable uses ultra pure, soft annealed copper and super low loss insulation
    • Gold-plated industrial grade PCB
    • Elma / Swiss - Input selector switches
    • VTC - volume transformer control, 4 channels / 42 position - electronic-relay system, custom made by ayon
    • This stepped volume control system has a channel balance within +/- 0.05dB.
    • Tantalum - The best sounding precision resistors 0,5% are everywhere, best resolution and lowest noise.
    • Rifa - Long life capacitors

Mechanical Construction
The high grade aluminum chassis impart a richer, more lustrous tonality with a cleaner background and less hash and grain.

All brushed anodized anti-vibration and non-magnetic chassis are fully assembled to the highest level of craftsmanship.

  • Improved heat ventilation chassis
  • Backlit front panel displays indicate level attenuation & input selection
  • 3 Platinum knobs with backlit glass pivot, custom-made by Ayon
  • The aluminum feet are a kind of acoustic absorber types
  • All front & rear panel descriptions are engraved
  • Ground switch
  • AC phase polarity control indicator
  • Volume & Mute function - RC
  • Metal remote commander
  • Chassis finish: black / chrome
