Product Description

Get the 'Breath of Life' from Your System

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.

“After more than ten months of constant use this sweet-honey of an amp continues to impress with its inherent ease and musicality….its warmth, natural textural and harmonic qualities, and open, airy presentation are very satisfying. Its got what I call ‘musical detail,’ in that everything comes through in a way that serves the musical whole, allowing you to enjoy and become immersed in each performance!”
- Wayne Garcia, The Absolute Sound, Golden Ear Award, February 2006

The VK-55 offers the same world-class automatic-bias circuit found in their reference tube 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 warm-up, aging or partial mismatching of tubes’ as well as fluctuations in line voltage.

Many of our customers have asked for a killer, 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 of you out there, the VK-55 is the answer to your 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 is available as either a 55 watt per channel stereo amplifier or a 110 watt per channel monoblock power amplifier. Start with a single stereo VK-55 and if you ever change speakers or simply want more power, you can buy a second amplifier and have your stereo unit easily updated to monoblock status.

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. Come by the musicdirect showroom and hear this amp for yourself! One listen and you will be hooked!
