Balanced Audio Technology VK-56 Power Amplifier
Compact Chassis, Outstanding Performance, Stunning Affordability The Balanced Audio Technology VK-56 represents the meticulous application of modern design principles to the development of a compact, affordable, and supremely easy-to-use vacuum-tube power amplifier that sets a new standard for musicality in its class. The result is a unique combination of fully balanced, all-triode design topology, automatic biasing of individual output tubes, and a marvelously simple upgrade path to monoblock operation—all in a chassis more compact than any previous BAT tube amplifier design. In addition, VK-56 is available with a silver color option that incorporates a silver front faceplate and matching rear arch.
Featuring a graceful rear arch that literally and figuratively raises the bar on industrial design, the BAT VK-56 arrives as the go-to amplifier for music lovers seeking the renowned manufacturer’s hallmark sound in a component that boasts rigorous design principles and a more affordable price point. Skimping on nothing that has made BAT a preeminent high-end company, VK-56 provides superb midrange clarity, power, and dynamics. Plus, all-triode topology and auto-biasing means it’s the easiest tube amp you could hope to own.
Features the Same High-Current Tube as BAT’s Flagship Power Amplifier
Many BAT customers asked for a smaller and more affordable tube amplifier that meets BAT's rigorous design standards while providing the breath of life to music characteristic of the BAT sound. VK-56 is the answer to their dreams. By using the same high-current dual-triode 6C33C-B tube employed in BAT’s flagship REX II power amplifier, VK-56 (55Wpc stereo, 110Wpc monoblock configuration) delivers the high-current kick required to drive even difficult low-impedance speaker loads. You can simply choose the stereo or monoblock version based upon your choice of speaker and room size. VK-56 can be upgraded to VK-56SE status at any time.
Intelligent Auto-Bias Design Makes Operation a Cinch
This power amplifier’s advanced engineering eliminates the traditional headache associated with most vacuum-tube power amplifiers—specifically, the constant need to set and readjust the proper bias of the output tubes—as VK-56 features an intelligent automatic bias design that adjusts for changing line voltage and aging tubes, with each output tube having its own dedicated bias circuit. The auto-bias circuit also ensures your VK-56 sounds wonderful within the first few minutes of listening. You’ll immediately experience the midrange clarity, power, and dynamics that have made BAT one of the most respected brands in high-end audio. All you need to do is listen!
