BAT VK-55SE Tube Power Amplifier

Take All Work and Worry Out of Owning a Tube Component With the Balanced Audio Technology VK-55SE Tube Power Amplifier

Stereophile Class-A Rated Design Features Enormous Power-Supply Energy Storage, Auto-Biasing, 6H30 SuperTube: BAT VK-55SE Tube Power Amp Soulful and Harmonic

Take the work and worry out of owning a tube amplifier with the Stereophile Class-A rated BAT VK-55SE tube power amplifier. The easiest-to-use high-performance tube design on the market, this BAT workhorse features auto-biasing so that you’ll never need to set and readjust the proper bias of the output tubes. A 6H30 SuperTube, paper-in-oil capacitors from BAT flagship models, and immense power-supply energy storage all translate into the kind of dynamics, transparency, realism, and midrange clarity audiophiles dream about hearing. Built to last lifetimes, the VK-55SE makes such visions a reality.

Retaining Existing Strengths and Adding New Benefits
The fully balanced, all-triode VK-55SE power amplifier retains all the strengths that make the VK-55 a stellar performer—including the world-class automatic-bias circuit found in BAT's reference REX II Power amplifier—while incorporating the 6H30 SuperTube into a completely revised first gain stage. This is the same tube used in BAT’s REX II models, and provides the VK-55SE with a more transparent, involving reproduction of the musical event. The VK-55SE also employs the same paper-in-oil capacitors used in BAT’s flagship amplifier designs, resulting in more natural and coherent sonics. Finally, the power-supply energy storage is increased to over five times that of the VK-55!

Improved Output Tube and Current Sources
Delivering 55Wpc in the stereo version or a robust 110Wpc as a monoblock, the VK-55SE power amplifier utilizes a 6C33C-B triode output tube that offers many times the current delivery of the 6550 tube used in many traditional tube amplifier designs. The VK-55SE also substantially improves its circuit topology by incorporating vacuum-tube current sources for the first gain stage of its design. Those installed in the VK-55SE provide a more soulful portrayal of harmonic texture and instrumental timbre.  Your recordings will simply sound more alive while simultaneously yielding greater finesse, grace and inner detail.

Intelligent Auto-Bias Design the Icing on the Cake

The VK-55SE’s advanced engineering eliminates traditional headaches 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-55SE 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-55SE sounds wonderful within the first few minutes of listening. Loaded with reference-grade improvements, the VK-55SE offers more magic by digging deeper into the raw emotional power that bestows music with transcendent grace and absorbing detail.

"The BAT had a sound that was always vivid, relaxed and liquid. The BAT's grain-free, uncolored, and quiet sound worked to reproduce music in a way that came dangerously close to the live experience!"
