Med Mercury II fortsätter evolution av Mercury förstärkarna ytterligare genom dramatiska förbättringar av andra generationen nätdelar och drivsystem teknologi. Den stoltserar med exceptionellt neutralitet, hög upplösning och en snabb och luftig klang med stor musikalisk sötma. En snabb och luftig tredimensionell ljudbild är självklarheter för denna extraordinära förstärkare.
Tre olika Effekt Triod-rör kan installeras i denna förstärkare. En teknisk uppdatering måste göras vilket kan utföras av leverantören. Fördelen för dig som kund är att kunna "trimma" förstärkaren upp till nästa effektnivå med samma förstärkare.

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. Today only few manufacturers still produce tubes for pure audio amplification; one of them is Ayon Audio with its outstanding single-ended triode power tubes (AA32B-S, AA52B-S and AA62B) based on the WE 300B.

 

Signal Path
We believe that the simplest circuits work best together with the shortest signal path. That is why our SE-Triode 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.

  • Logical sequenced soft-start power up for extended tube life
  • Tube and electronic protection circuit system
  • 0dB negative feedback (of any kind)
  • DHT
  • Ultra short signal path
  • Simplest direct circuit path for purest musical sound and high reliability
  • 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
  • External static bias adjustment
  • No followers or buffers in the signal path
  • High quality parts throughout
  • Fully hand assembled to insure the highest level of craftsmanship
  • Selector switch engages relays located near RCA jacks to switch all inputs

 

Power Supply
Single ended amps are more susceptible to power supply aberrations than push-pull amplifiers. The power supplies have been further 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 and it is a critical attribute for a single-ended amplifier. 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 low noise –insulated power transformers
  • Power transformers are encased, excellent damped and RFI/EMI shielded
  • Innovative power supply provides a high speed energy delivery on transients
  • Dual choke filtered power supply for Ayon AA52B-S
  • Dual choke for pre and driver stage
  • Tube regulated power supply (5U4G)
  • Separate and isolated power supplies over each stage of amplification
  • Regulated DC filament supplies with soft start
  • AC power line filter to avoid noise and hash from entering into the unit.
  • High capacitance energy storage.
  • Current in-rush limiting
  • Auto sequencing - Power on cycle completes in 1 minute

 

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. Such 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 cannot be over emphasized.

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

 

Output Transformer
The super-wide bandwidth output transformer's major strength is that it can deliver the current in the bass, while at the same time maintaining the speed in the high frequencies, dramatically improving the square wave response of the amplifier. The effect is a much more natural and relaxed sound with much better clarity, resolution and fluidity.

  • Super-wide bandwidth high performance output transformer
  • High efficiency with low insertion loss for optimal current and voltage transfer
  • Multiple tight layering and coupling for extended frequency response
  • Output transformers are sealed with an anti-resonance compound material

 

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.

High Grade Speaker Bindings
The new ayon gold plated solid body Postspeaker binding posts provide performance levels that are truly in the very High End. The solid body construction ensures that there is no gap or breach in the flow of electrons. The gold plating provides for superior contact and resistance to oxidation. These binding posts are chosen primarily for their sonic performance, edging out even more expensive counterparts.
