These albums receive our ULTRASONIC Audio Desk Pro restorative treatment. This incredible machine safely removes age old contaminants from deep within the grooves and exposes the original vinyl surface. The result is significantly reduced surface noise and higher fidelity during playback. Enjoy less pops and clicks with more refined highs/lows and better note separation. The original sleeves are safely stowed inside the album covers and a new premium archive grade sleeves are included to protect the revitalized media.
