BALANCED AUDIO TECHNOLOGY VK-43SE Preamplifier
A NEW BENCHMARK IN SOLID-STATE PREAMPLIFIER DESIGN
Combining BAT’s trademark high-current Unistage topology with the transformer-coupled outputs anchoring all Balanced Audio Technology Special Edition preamplifiers, VK-43SE establishes a new performance benchmark. Upgraded output transformers work in conjunction with a symmetrical N-channel Unistage gain block (biased at an extraordinary 250ma) to deliver BAT’s hallmark high-current operation. Fully balanced dual-mono construction and more than 55,000uF of power-supply capacitance yield instantaneous response to the most demanding signal requirements. Second-generation oil-filled capacitors provide increased purity to the elegant Unistage circuit, completing BAT’s new flagship solid-state preamplifier.
UNISTAGE TOPOLOGY, SECOND-GENERATION OIL-FILLED CAPACITORS, MOSFET CIRCUIT
Simplicity of design continues to be a hallmark of Balanced Audio Technology’s purist approach. Since the signal in VK-43SE is transmitted through only one gain stage, the design is free from the negative artifacts attributable to both extremes of modern preamplifier design—passive preamplifiers on one end of the spectrum, and multi-stage buffered active circuits on the other. In addition, second-generation oil-filled capacitors dramatically lower VK-43SE’s noise floor and present a grain-free, textured, and refined portrayal of musical harmonics. A high-current N-Channel MOSFET circuit ensures ultimate symmetry of the audio signal and accounts for tube-like coherence, textural liquidity, and cutting-edge transparency.
READY FOR YOUR PERSONAL TOUCH—AND THE WORLD’S FINEST MUSIC SYSTEMS
Easy to use right out of the box, VK-43SE is just as user-friendly to customize. You can dim the display from the comfort of your chair by using the BAT remote. Fade music at the touch of a button. Switch phase to see if a recording is made in reverse absolute polarity. Even name your sources. VK-43SE also employs a proprietary electronic shunt volume attenuator that offers 140 steps of 0.5dB resolution. Also available with the optional VK-P20 phono module designed to compete with external phonostages twice its price, VK-43SE stands at the ready to anchor the finest reference systems.
