Ayon Audio Mercury II Amplifier

Ayon Audio Mercury II Integrated Amplifier

The Mercury II continues the evolution of the Mercury amplifier by once again offering dramatic improvements to its completely revised second-generation power supply and driver technology. The Ayon Mercury II is the little brother of our famous “Crossfire” amplifier. It exhibits all well known Ayon magic and qualities. This amplifier offers exceptional tonal neutrality, high resolution and punchy-airy timbre with great musical sweetness. A quick uncoloured bass and a spacious 3D soundstage are self-evident for this remarkable amp.
Three different Triode Power tubes can be used in this amplifier. A technical update is necessary, which can be installed by the distributor. The advantage for the customer is to tune up into the next power class using the same amplifier.

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.
