The BAT VK-53SE Preamplifier has been discontinued. Transformer-coupled outputs for the utmost in musical purity and coherency. The VK-53SE is the finest single-chassis preamplifier ever offered by Balanced Audio Technology. It features 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 the 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.

User-friendly interface and custom-tailored options

Boasting one of the best and most flexible user interfaces in the high end, the VK-53SE features myriad customizable options ranging from dimming to fading and source-naming. The 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, the VK-53SE is your new reference.

Fire it up: Eight 6H30 supertubes under the hood

More than a decade ago, BAT introduced the world to the 6H30 SuperTube. The 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 the 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.
