Block Audio Mono Block SE Class-A Monoaural Power Amplifier

Do not get confused with its elegant-looking silhouette. This pair of amplifiers will make your loudspeaker go outrageously wild. Inside of the aluminum body, there are 90 kilos of pure sound perfection hidden 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’ll get a truly unforgettable experience. Works great alone, but plugging it with the Block Audio preamplifier will get you to a whole new level that cannot be explained, but needs to be experienced.
