BALANCED AUDIO TECHNOLOGY VK-P12SE WITH SUPERPAK PHONO STAGE
THE LARGEST-VALUE OIL CAPACITORS IN ANY BAT COMPONENT
Reaching dramatic new performance levels while pristinely preserving the delicate signals generated by modern cartridges, the VK-P12SE SuperPak represents a new reference for phonostages. Building on knowledge gained during the design of BAT’s groundbreaking REX amplification products, the second-generation SuperPak yields a far more open sound, with a more coherent portrayal of musical texture from the lowest to the highest frequencies—and an astonishingly vibrant, three-dimensional soundstage. The SuperPak replaces electrolytic capacitors in the most critical first two gain stages with the largest-value oil capacitors ever employed in a BAT design. Boasting state-of-the-art engineering achievements, individual technical advancements, and awe-inspiring synergy, VK-P12SE SuperPak pays priceless dividends on your investment in vinyl.
YEARS IN THE MAKING: A "TRANSFORMATIONAL" TRANSFORMER-COUPLED OUTPUT STAGE
Like the elite VK-33SE, VK-53SE and REX II preamplifiers, the VK-P12SE SuperPak features a transformer-coupled output stage. This new design replaces BAT’s venerable Six-Pak of output capacitors with custom-designed output transformers. In order to achieve this “transformational” goal, years were spent prototyping and testing various alternative output transformer designs. All the work paid off: BAT’s new transformer-coupled output stage proves substantially superior to any capacitor in maintaining a purity of signal transmission. Electrically, these output transformers significantly improve the VK-P12SE’s performance in every measured respect. Sonically, they offer improvements in every area of musical reproduction.
MATCHLESS ENGINEERING, UNRIVALED PARTS QUALITY, NONPAREIL OPERATION
The heart of the VK-P12SE SuperPak is an all-tube zero-feedback design that combines the benefits of balanced operation with complementary vacuum-tube current sources. Dual-mono construction and enormous energy reserves are matched by extensive flexibility in cartridge loading. The first gain stage achieves a very low noise floor via premium Vishay Bulk Foil resistors that replace metal film resistors. An upgraded power supply contributes to more responsive, visceral bass. Vacuum-tube current sources further improve the linearity and yield a more open, textured sound. Dual 6SN7 vacuum tubes act as current sources for the second gain stage. A differential RIAA network ensures all your records will sound the way the recording engineer intended, permitting ease of adjustment and improved common mode noise rejection. Plus, second-generation step-up transformers provide as much as a 20db improvement in signal-to-noise ratio in comparison to direct mode operation. With up to 80dB of gain available, no signal is too small. All you have to do is listen.
