Balanced Power Amplifier
The Balanced Audio Technology VK-55 represents BAT's latest application of modern design principles to the development of a compact, affordable, yet supremely easy to use 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, combined with selectable feedback, automatic biasing of individual output tubes, and a marvelously simple upgrade path to monoblock application all in a chassis that is 33% more compact than any previous BAT tube design! More importantly, the VK-55 is eminently affordable as well.
The VK-55 offers the same world-class automatic-bias circuit found in our reference VK-150SE tube power amplifiers. This advanced design eliminates the traditional headache associated with the ownership of vacuum tube power amplifiers; the constant need to set and readjust the proper bias of the output tubes. Just turn the VK-55 on and play music! The automatic bias circuit automatically compensates for tube warmup, aging or partial mismatching of tubes as well as fluctuations in line voltage.
Many of our customers have asked for a smaller and more affordable tube amplifier that meets BAT's rigorous design standards while providing the breath of life to music that is characteristic of the BAT sound. For those customers, the VK-55 is the answer to their dreams! Moreover, by using the same high-current dual-triode 6C33C-B tube employed in our flagship tube amplifier, the VK-55 delivers the high-current kick needed to drive more difficult low-impedance speaker loads.
The VK-55 offers the midrange clarity, power, and dynamics that have made BAT one of the most respected brands in high-end audio. The VK-55 is able to present a magical open window to the original performance - and a closer emotional connection to the artistry of the music. Visit your BAT audio specialist today.
