Cary Audio CAD300SEI

Used 7/10



The 300SEI was a musical revelation, providing a totally involving and musically euphoric experience night after night. The 300SEI excelled in the most important areas: harmonic rightness, total lack of grain, astonishing transparency, lifelike soundstaging, and a palpability that made the instruments and voices seem to exist in the listening room. Beyond these specific attributes, the 300SEI communicated the musical message in a way that went straight to the heart.
