BALANCED AUDIO TECHNOLOGY VK-55 VALVE POWER AMPLIFIER
COMPACT CHASSIS, OUTSTANDING PERFORMANCE, STUNNING AFFORDABILITY
The Balanced Audio Technology VK-55 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. Beyond providing outstanding musical performance, the VK-55 is eminently affordable as well.
USES SAME HIGH-CURRENT TUBE AS BAT FLAGSHIP POWER AMP
Many BAT customers asked for a smaller and more affordable tube amplifier that meets our rigorous design standards while providing the breath of life to music characteristic of the BAT sound. The VK-55 is the answer to their dreams! By using the same high-current dual-triode 6C33C-B tube employed in our flagship REX II Power amplifier, the VK-55 (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.
INTELLIGENT AUTO-BIAS DESIGN MAKES USE EASY
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 the VK-55 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 that your VK-55 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!
