BAT VK 655SE Amplifier

PURIST APPROACH, TRUE DUAL-MONO DESIGN

BAT_VK_655SE_Front light

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 sound stage 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.

MASSIVE POWER: ENOUGH ENERGY TO LIFT MOST SPEAKERS OFF THE GROUND

The VK-655SE’s elegant signal path follows BAT’s purist approach of using zero negative feedback to achieve the goals of wide bandwidth and circuit linearity. Its circuit is based entirely on N-Channel MOSFET devices. A high-current design that offers a robust 600 watts per channel into a four-ohm load, the VK-655SE easily drives most any speaker ever made. The monoblock version doubles these figures, and contains a whopping 1800 joules of energy storage—enough to lift most speakers over one meter off the ground! High power—combined with high-energy storage—produce the dynamic sound that is a BAT hallmark.

SUBLIME MUSIC REPRODUCTION: SPEED, SLAM, DYNAMICS

Dynamic responsiveness remains the recognizable difference between live and reproduced music. The VK-655SE couples quickness, slam, and dynamic range with an extended, deep soundstage and an exquisite fidelity to the timbre and texture of instruments and voices.  Indeed, the sound of the VK-655SE and REX II power amplifiers converge upon the same ultimate goal: sublime reproduction of music independent of the devices employed.  By utilizing only the highest-grade parts throughout, BAT allows the VK-655SE to yield supremely transparent insight into any music you play. It’s time you experienced such beguiling sonics for yourself.
