The VK-255SE power amplifier represents Balanced Audio Technology’s hallmark out-of-the box approach to audio circuit design. Unlike most solid-state amplifiers that feature four or more gain stages in a high-feedback push-pull configuration, the VK-255SE features only two gain blocks in a high-power, zero feedback, and purely symmetrical design. Available as either a stereo or monoblock unit, the VK-255SE has the warmth and texture typically associated with the finest vacuum-tube designs combined with the dynamic capability of the best solid-state offerings.
