The Ayon Audio Spirit is a high-end stereo integrated amplifier operating in pure Class-A with zero negative feedback. It uses KT88 tubes in a push-pull configuration and can be switched between triode mode (2 x 40W) and pentode mode (2 x 65W). The amplifier features a manual easy bias system, multiple line inputs, a pre-out for subwoofer connection, and a remote control for volume and mute functions. It is designed with short signal paths without solid-state devices in the audio path to preserve sound purity. The build quality is impeccable with a brushed aluminum chassis and chrome transformers, weighing approximately 29-31 kg. The Spirit is noted for its transparent, dynamic, and holographic soundstage with deep bass performance. It is suitable for driving 4 to 8 ohm loudspeakers and includes speaker taps for impedance matching. The power supply is refined for low noise and high transient energy delivery, with separate isolated supplies for input and output stages. The amplifier is designed for audiophile use, prioritizing sound quality over convenience features, with the power switch and bias controls located on the back panel.
