The Finest Single-Chassis Preamplifier BAT Ever Created: Balanced Audio Technology VK-53SE Offers Ultimate in Tonal Purity, Noise Isolation, and Signal Integrity

Transformer-Coupled Outlets, Eight 6H30 SuperTubes, and Customizable Features Among Feature Set: BAT VK-53SE Tube Linestage Preamp Sounds Utterly Amazing

Forget the fancy introduction, we'll come right out and say it: The Balanced Audio Technology VK-53SE tube linestage preamp is the finest single-chassis preamplifier BAT ever created. Bolstered by eight 6H30 Supertubes, it offers the ultimate in tonal purity, noise isolation, and signal integrity. Its transformer-coupled, high-current, single gain-stage topology is abetted with custom-designed transformers that significantly improve the ability to drive low-impedance loads. You'll hear greater dynamics, transparency, top-to-bottom extension, and arrestingly coherent music portrayals. Truer Frank. Deeper Miles. Clearer Bob. More everything.

Transformer-Coupled Outlets for Utmost Musical Purity, Coherency
VK-53SE features a transformer-coupled, high-current, single gain-stage topology. The transformer-coupled outputs catapult the performance of this fully balanced, zero-feedback design to a higher level. These transformers replace BAT's venerable Six-Pak of output capacitors with custom-designed amorphous core output transformers. Each is encapsulated within a mu-metal shield for the ultimate in signal purity and noise isolation. Electrically, the custom transformers significantly improve VK-53SE's ability to drive low-impedance loads. Sonically, they offer greater dynamics, transparency, top-to-bottom extension, and a more coherent, organic portrayal of music.

Fire It Up: Eight 6H30 SuperTubes Under the Hood
More than a decade ago, BAT introduced the world to the 6H30 SuperTube. VK-53SE continues to proudly use eight 6H30 SuperTubes to form an extraordinarily high-current, low-impedance drive capability. As BAT wrote upon introduction, "comparing the 6H30 tube to a standard 6922 is like comparing a Formula 1 race car to a family sedan." In VK-53SE, the signal is effectively transmitted through only one gain stage. The Unistage circuit provides the ultimate simplicity of amplifying the incoming signal only once, while using no global feedback to double back on the straight-through signal integrity.

User-Friendly Interface and Custom-Tailored Options
Boasting one of the best and most flexible user interfaces in the high end, VK-53E features myriad customizable options ranging from dimming to fading and source-naming. VK-53SE can also be fully upgraded to the REX II preamplifier. And, you can always get the volume just right. It employs a proprietary electronic shunt volume attenuator that offers 140 steps of 0.5dB resolution. Discrete metal film resistors bleed the unused signal to ground. From the deepest bass, to extraordinary dynamics, as well as a greater sense of layered transparency, VK-53SE is your new reference.
