VK-P90 Phono Preamplifier

Third-Generation SuperPak Provides Utmost Transparency
VK-P90 features Balanced Audio Technology’s new, third-generation SuperPak in its power supply design. It represents a significant rethinking of what is possible from an energy storage device. For the first time, the BAT SuperPak features hybrid construction that incorporates two capacitors built and potted into each individual shell.

An additional silver-in-oil capacitor—the finest-quality capacitor offered at any price—is used as part of the Gen 3’s construction. The two capacitors are then assembled into a new low-resonance shell. The result: Low-level detail is revealed in a clear and unforced manner, while the overall sound takes on a beguiling sweetness and naturalness from top to bottom.

Fully Balanced, All-Tube Design Offers Analog Bliss
With VK-P90, you get an all-tube zero-feedback design that combines the benefits of balanced operation with complementary vacuum-tube current sources. Its dual-mono construction and enormous energy reserves are matched by extensive cartridge-loading flexibility.

The first gain stage achieves a very low noise floor via premium Vishay bulk foil resistors that replace metal film resistors in critical areas. An upgraded power supply joins the transformer-coupled output stage in contributing to immersive transparency and responsive, visceral bass.

Vacuum- tube current sources further improve the linearity and produce a wide-open, textured sound. In addition, a differential RIAA network ensures all your records will sound the way the recording engineer intended, all the while permitting ease of adjustment and improved common-mode noise rejection.

Plus, the VK-P90’s 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. Analog bliss awaits.

Transformer-Coupled Output Stage Delivers Superior Purity
Like the elite VK-80, VK-90, and REX 3 preamplifiers, VK-P90 features a transformer-coupled output stage. The result of countless prototypes and tests, it proves substantially superior to any capacitor in maintaining a purity of signal transmission. Electrically, the output transformers significantly enhance every measured respect, while sonically, they offer improvements in all areas of musical reproduction.
