VK-90 Tube Preamplifier
Featuring transformer-coupled, high-current, single-gain stage topology, VK-90 is the finest single-chassis preamplifier ever created by Balanced Audio Technology.
Wound with Cardas’ finest copper wire, the second-generation transformer-coupled outputs catapult the performance of this fully balanced, zero-feedback design to a reference level. Each transformer comes encapsulated within a mu-metal shield for the ultimate in signal purity and noise isolation.
Electrically, these second-generation transformers improve VK-90’s ability to drive low-impedance loads. Sonically, they offer greater transparency than the already revered performance established by BAT’s first-generation transformer design.
