Balanced Audio Technology VK-90 Preamplifier
Best reference-level preamplifier for audiophiles seeking pure, uncolored sound reproduction.
This preamplifier strips away the complexity of modern signal chains to deliver a startlingly pure, uncolored sound. By committing to a single-stage, zero-feedback design, it sacrifices the versatility of more feature-heavy units to achieve a level of sonic transparency that feels almost invisible.
