If you think every mass production plant is burning CD's a 1x speed you should re-invest in ADAT's . Every Cd I've produced in the last four years has had CD burned at 4x in MLCD with PT. Could it be that some of the cheeper quality Cd burners are more prone to errors and sound denagration? I have the same burner ( yamaha ) that every Pt rig has in nashvile and we all are doing the same. I just wanted someone from a mastering lab to commit, or have someone address this in an upcoming audio mag. Any offers??
