The RMB-1555 is an impressive multi-channel amplifier with an output power conservatively rated at 120 Watts per channel into 8 ohms (with all channels driven!). With most only demanding speakers placed in exceptionally large spaces, the RMB-1555 exerts the kind of precise control that presents both the details and the explosion correctly from the softest flute notes to the subterranean rumble of an impending apocalypse.

The RMB-1555 uses a high-power toroidal transformer, paired with discrete output transistors with higher thermal stability and absence of the limitations that characterize integrated circuits. The Class AB amplifier layout ensures the best balance between output power and thermal efficiency.
