Ayon Audio's New Orthos II XS Monoblock Tube Amplifiers

   Ayon Audio's Orthos II XS GEN 4 monoblock amplifiers ($32,000) will be at AXPONA 2018 within room 1633. The company is proud to introduce their latest third-generation KT150 mono power amplifier, which provides true balanced or single-ended operation combined with the ability to deliver 300 Watts per channel.

All the gain stages and power stage have been re-designed and optimized as well to provide for the shortest signal path and the most direct signal flow. The result is a significant advance in sonic performance, wider and deeper holographic soundstage with more fine details and greatly improved powerful bass punch, dynamics and outstanding life-like performance free of compression effects or dynamic limitations. One of the absolutely best sounding KT150 power amplifier in the world.

Full-featured true balanced vacuum tube mono power amplifier Switchable between pentode and triode mode Ideal also for more difficult loudspeaker loads. Furthermore, Ayon Audio believes 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.

The power supplies have been further refined over previous models 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. 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.

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.
