Class-A Monaural Power Amplifier

Mono Block

Do not be confused by its elegant looking silhouette. This pair of amplifiers will make your loudspeakers go outrageously wild. The aluminum body conceals 90 kilos of pure sound perfection, delivering 500 W out of which 200 W are in pure Class-A. Add 120 dB of signal/noise ratio and 5 000 damping factor and you will get a truly unforgettable experience. Works great alone, but plugging it with the Block Audio preamplifier will give you to a whole new level that cannot be explained but only experienced.
