Balanced Audio BAT VK-32SE Special Edition Tube Preamp Picture and Description:
I am the original owner of this Balanced Audio Technology VK-32SE (Special Edition) all-tube linestage preamplifier with SUPER-PAK oil capacitors and remote control option. I purchased it new from my local BAT dealer in 2008. This linestage is in excellent condition - all operations work perfectly and it sounds fantastic. I can find no scratches or mark on the face or chassis. It is still running the original tube set (4 x 6H30 and 2 x 6C19), but I am including a new spare set, purchased from Jim McShane who matched and tested for low noise/microphonics ($166 for new Sovtek set). Also included with the BAT preamp is the solid-aluminum remote control, manual and original box. The BAT VK-32 SE prices at $8495 new - this is an opportunity to purchase a US-built reference tube preamplifier at a significantly lower price. Please see my other auctions for a BAT VK-250SE power amplifier that I used with this preamp. BAT VK-32SE Features and Specs: The VK-32SE builds on a solid foundation, using proven ideas and design solutions previously incorporated in other Balanced Audio Technology products. It continues the line of Unistage products based on a single gain stage, incorporating no buffers or followers and no global negative feedback. The ultimate simplicity of this topology has been widely acclaimed and accepted as an industry standard. The strength of the VK-32SE starts with its immense power supply, in dual mono configuration, using separate, oversized toroidal power transformers for each channel. The power supply generates symmetrical high voltage rails for the active gain stage, allowing it to operate linearly and with low distortion over a tremendous signal range. Before reaching the gain cell, the power supply voltages undergo several stages of filtering, using C-multipliers on both positive and negative rails. The final stage of filtering, the one directly connected to the gain stage, consists of BAT’s custom oil capacitors as part of its monstrous SUPER-PAK. This approach guarantees that only the highest quality capacitors work in conjunction with the amplification devices. The differential gain stage is composed of two 6H30 SuperTubes per channel, supported by vacuum tube current sources, and incorporating Vishay Bulk Metal Foil load resistors. The VK-32 SE volume control provides broad range of adjustment with 140 steps of .5dB resolution, resulting in essentially a continuous feel. Based on shunt topology, and using 16-bit digital control, it utilizes Vishay resistors as its pass devices. Custom oil-filled capacitors are used at the output, resulting in an unmatched transparency and clarity of sound. This whole package utilizes BAT’s powerful user interface, allowing customization of each input individually, that keeps receiving universal acclaim from customers and reviewers alike! Like all Balanced Audio Technology preamplifiers, the VK-32SE can be ordered with an optional full function remote control (option is on this preamp).
