About SW1X Audio Design

SW1X Audio Design (pronounced 'As One X Audio Design') is a UK-based manufacturer specializing in extreme, high performance audio equipment, particularly known for its hand-assembled valve amplifiers, DACs, and audio components. The brand's philosophy centers on resurrecting the 'soul of music' in audio playback, prioritizing musicality and emotional connection over technical convention. All products are crafted in Essex, England using the finest materials, and eschew common digital processing (no oversampling, jitter reduction, or noise-shaping) in favor of analog-domain filtering for pure PCM conversion. Founded by Dr. Slawa Roschkow, SW1X offers a scalable portfolio across multiple performance levels, catering to audiophiles seeking state-of-the-art, musical, and timeless audio reproduction.
