VK-23SE

On the surface, VK-23SE is Balanced Audio Technology entry-level solid-state preamplifier. Yet it’s packed with much of the same technology found in the company’s flagship solid-state and vacuum-tube preamplifiers. VK-23SE combines BAT’s trademark high-current Unistage topology with the transformer-coupled outputs that anchor every BAT Special Edition preamplifier. They work in conjunction with a symmetrical N-channel UnistageTM gain block to provide BAT’s hallmark performance.

VK-43SE

Combining BAT’s trademark high-current Unistage topology with the transformer-coupled outputs anchoring all Balanced Audio Technology Special Edition preamplifiers, VK-43SE establishes a new performance benchmark. Upgraded output transformers work in conjunction with a symmetrical N-channel Unistage gain block (biased at an extraordinary 250ma) to deliver BAT’s hallmark high-current operation.

VK-REXII Preamplifier

The culmination of nearly two decades of design, the fully balanced REX II preamplifier represents the pinnacle of Balanced Audio Technology¹s purist approach to building a statement control center without peer. Featuring a vacuum-tube power module and separate control module, this groundbreaking two-box component features a transformer-coupled output stage (aka T-REX). The latter replaces BAT¹s Six-Pak of output capacitors with custom-designed amorphous core output transformers. Sonically, they offer greater dynamics, transparency, top-to-bottom extension, and a more organic portrayal of music.

VK- 53SE

The VK-53SE is the finest single-chassis preamplifier ever offered by Balanced Audio Technology. It 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.

VK-33SE

With its new transformer-coupled outputs and superb user interface, the VK-33SE offers both extremely dynamic, transparent renditions of musical events and the industry’s best ease-of-use versatility. The result of intense research, each of the preamplifier’s transformer-coupled outputs is encapsulated within a mu-metal shield, a design substantially superior to any capacitor in maintaining purity of signal transmission. True to its heritage, the VK-33SE uses the 6H30 SuperTube to form a high-current, low-impedance gain stage.

VK-33

BAT's VK-33 preamplifier incorporates changes to its power supply formerly reserved for Special Edition models. New SE power-supply transformers provide marked increases in dynamics and speed. In addition, the signal in the VK-33 is transmitted through only one gain stage. As such, it’s free from the negative artifacts attributable to both extremes of modern preamplifier designs: passive preamplifiers at one end of the spectrum and multistage, buffered active circuits at the other.
