Celebrating over 25 years of cutting-edge audio design, the VK-3500 marries a ‘SuperTube Unistage’ preamplifier with a solid-state power section generating a robust 150 watts per channel into 8-ohm loads, doubling into 4-ohm loads. As per the reference 6H30 SuperTube Unistage used in the flagship REX 3 preamplifier, the signal is transmitted through only one gain stage with zero feedback. The VK-3500’s output stage employs a zero-feedback symmetrical bipolar class AB design that perfectly complements the 6H30 tube-based preamplifier by providing high current capability as well as wide bandwidth for the ultimate in transparency and high-end extension.
