Eon Art Hadron – a three-block integrated mono amplifier

The Canadian company Eon Art has presented an extraordinary solution – the Eon Art Hadron integrated amplifier, which is designed in three blocks for each channel! At first glance, the system looks like it uses two power supplies, but this is not so. One of the modules is responsible for filtering alternating current and converting it into direct current. The second module is, in fact, the power supply of the system. The third is an amplifier. This solution was realized after the company conducted a series of studies on the problems of alternating current for powering high-quality audio sources.

Eon Art Hadron uses a redundant configuration in each circuit of the path, dividing it as much as possible and achieving outstanding sound quality. Each of the blocks is designed in a case measuring 43.5 x 43.5 x 32 cm, the total weight of the system for one channel is 113.22 kg. Exceptional attention has been paid to shielding and filtering the signal - auxiliary power supplies use a medical IEC60601-1 filter and a Toroidy isolation transformer. The main power transformer is filtered by a circuit based on bipolar capacitors and a DC blocker; the preamplifier section is also filtered by a Toroidy Supreme.

The Eon Art Hadron amplifier section operates in hybrid class A + D, the preamplifier section is tube (Philips SQ E8CC, etc.), power supply uses tubes too (JJTesla 5AR4, etc.). The output power reaches 400 W into 8 Ohms or 700 W into 4 Ohms. Distortion does not exceed 0.1518%, which is very effective for the chosen circuit design.
