BALANCED AUDIO TECHNOLOGY VK-23SE Preamplifier
STEEPED IN TECHNOLOGY FOUND IN BAT’S FLAGSHIP DESIGNS
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. An easy-to-use programmable user interface and discrete 140-step shunt volume control are the same as those found on BAT’s top-of-the-line REX II preamplifier—right down to the Vishay bulk foil resistors used in the volume-control circuit.
FULLY BALANCED, UNISTAGE TOPOLOGY, PROPRIETARY VOLUME CONTROL
Naturally, VK-23SE is fully balanced. The signal in VK-23SE is transmitted through only one gain stage, leaving it free of the negative artifacts attributable to both extremes of modern preamplifier design. Its circuit is based entirely on N-Channel MOSFET devices. VK-23SE offers another rare advantage in that identical devices—in identical circuit configuration—handle both sides of the audio waveform and ensure ultimate symmetry of the resulting signal. Employing the same sophisticated volume-control circuit as the REX II preamplifier, VK-23SE also boasts a proprietary electronic shunt volume attenuator that offers 140 steps of 0.5dB resolution for precise control.
TUBE-LIKE SONICS, SUPERB USER INTERFACE, CUSTOMIZABILITY, OPTIONAL PHONO MODULE
Offering relief from the fatiguing sonics associated with most solid-state preamplifiers, VK-23SE combines a tube-like presentation with see-through transparency and a bell-like purity of tone. Simple to use out of the box, VK-23SE is just as easy to customize. You can dim the display from the comfort of your chair by using the BAT remote. Fade music at the touch of a button. Switch phase to see if a recording is made in reverse absolute polarity. Even name your sources. VK-23SE can even be ordered with the outstanding VK-P20, a solid-state phono module that hangs with external phonostages twice its price.
