Description from Manufacturer

The MB-100 has been compared, by audiophiles, to amplifiers that cost thousands of dollars. This is a robust almost bulletproof no maintenance design for 2ch music or HT applications.

The powerful MB-100 monoblock amplifier will easily drive most loudspeaker systems.

The MB-100 is DC coupled (no capacitors in the signal path), it is dead silent between music content (even at full volume), it has crystal clear smooth midrange and sparkling highs, and its powerful rich bass can shake a building!

The MB-100’s sound is quite transparent, very smooth and highly detailed.

The MB-100 was designed to play loud with only 0.014% THD+N @ 4 ohms at full rated continuous power. Music program peaks of more than 240 watts have been measured into 4 ohm speakers.

The MB-100 is compact at 6.5"W x 7.0"H x12.8"D and weighs in at 23 Lb. It sounds like a much larger amplifier due to its oversized 400 Watt power supply, large reservoir capacitors, and custom designed high current 9 lb silicone steel shielded low noise toroidal transformer.
