Audio Research SP-15 // Vintage / Hybrid Tube Dual Chassis Preamplifier / New Tubes

Audio Research SP-15 // Vintage / Hybrid Tube Dual Chassis Preamplifier / New Tubes

The Audio Research SP-15 is a ’90s-era hybrid preamp built for detail lovers and vinyl romantics alike. It marries solid-state precision on the line stage with the glow of three 6DJ8 tubes in its phono section, delivering music that’s both clean and captivating. You get a sweet balance of surgical clarity and tube soul, with specs to match: vanishingly low distortion, ultra-wide frequency response, and a whisper-quiet noise floor. The onboard phono stage is highly regarded—dynamic, uncolored, and adjustable to suit a wide range of cartridges. With full-featured controls, balanced outputs, and that unmistakable Audio Research build, the SP-15 is as much a reference tool as it is a musical storyteller.
