I recorded the original CD on to Yamaha CDR-HD1500 harddrive, then used a Quadri Beam Ultra Clarifier on one side, recorded again, and then A-B compared. It definitely was better, clearer, more detail, less veiled on my system. Then did both sides, and was even better. Quadri is supposed to be noticeably better than the dual beam.
After about 800 CD's, the motor has quit. I am buying a new one.
