According to Ayon Audio, the fully balanced design KT150 valve stereo power amplifier took years of development and refinement resulting in a unique minimalist true balanced circuit topology to produce an accurate and seductive holographic soundstage.

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.

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". Ayon Audio also use electrolytic capacitors with much larger storage capacity to make up for the loss in filtering when using resistors in lieu of inductors.

Boris Granovsky, of Absolute Hi End, the Australian distributor for Ayon Audio told StereoNET:

Musical finesse with fine details and powerful performance has been combined without compromise into one convenient chassis. We are confident that value and musical performance is outstanding and the Spirit PA is setting a new standard in its price class.
