The RMB-1555 is a remarkable multichannel amplifier with power output conservatively rated at 120 watts per channel into 8 ohms (all channels driven!). With all but the most demanding speakers located in extraordinarily large rooms, the RMB-1555 exerts the kind of precise control that presents both nuance and bombast correctly from the faintest flute overtones to the subterranean rumble of an approaching apocalypse.

The RMB-1555 employs a high current, toroidal transformer matched to discrete output transistors with their higher thermal stability and freedom from the designed-in compromises that characterise their integrated circuit cousins. The Class AB amplifier configuration assures the best balance between power output and thermal efficiency.
