901s were the"irresistible perfume" of (unsuspected) audiophilia. That & Dynaco A-25s. After hearing 901s in a college dorm room, then at an audio purveyor demo, not long after graduation I saved for a Bose receiver plus 501s, later with trade-in affordance 901s Mk IV, pressed into service, for apartment parties . Very fond memories of that time, the Bose gear. Welcome to the forum stick around.
