Yamaha has once again innovated with a new approach to amplifier design - and bad robot is the first to carry it! This is an entirely new floating and balanced power amplifier that uses power transistors with the same polarity that are not complementary. This allows the amplifier to achieve complete symmetry of pullable operation at the output stage and permits full balanced transmission (amplification) from the input jack to just before the speaker jack — a feature that has long been the dream of audiophiles.
