The Ayon Audio Polaris III is a sophisticated tube preamplifier from Austria, operating in pure Class A with triode-pentode tubes (C3M and 6H30). It delivers a maximum output of 40 V RMS at 1 kHz with a signal-to-noise ratio greater than 96 dB and extremely low harmonic distortion (<0.01% for line inputs, <0.1% for phono). The frequency response spans from 0.5 Hz to 400 kHz, ensuring exceptional audio fidelity. It includes 5 line RCA inputs, 1 phono MC input, and 1 XLR input, with outputs of 2 RCA and 1 XLR. The preamplifier uses a high-quality AC Regenerator power supply to minimize electrical noise and features precision components such as Lundahl transformers and Swiss Elma input selectors. The unit is housed in two chassis (preamp and power supply), each measuring approximately 50 x 43 x 11 cm and weighing a combined 33 to 44 kg depending on configuration. Reviews highlight its neutral, dense, and very natural sound with excellent spatial presentation and tonal richness, making it a top-tier choice for high-fidelity audio systems.
