The fully balanced VK-655SE power amplifier is the ultimate expression of BAT amplifier engineering. Available in stereo or monoblock configuration, it features only two gain blocks in a high-power, zero feedback, and purely symmetrical design. A true dual-mono component featuring independent channel assemblies, power transformers, and separate power cords for the left and right channels, the purist approach-based VK-65SE yields maximum soundstage width and depth. Finite micro- and macro-dynamics are reproduced with ease. A revised power supply incorporates the same second-generation oil-filled capacitors used in BAT’s flagship REX II preamplifier, dramatically lowering the noise floor and portraying grain-free, extra-refined harmonics.
