PSVANE's 274B-Z rectifier tube offers a soft, warm sound, full and natural, with good balance and no background noise. PSVANE offers us a tube with a more pronounced analog texture than that of classic tubes, with voices more prominent than usual and an overall sound evocative of vinyl's own texture.
