i know the manufacturers say iits worth it bcause they want you to pay the extra money. but do they actualy make a noticeable difference to the sound quality? Some friends and I at school are recording people using the schools studio and putting together a CD which we are planning to sell in aid of the recent asian Tsunami disaster, would it be worth buying special CDs for this? also i have a printer that can print onto CDs. ive been looking for Audio printable CD-rs but there dont seem to be any on the web. Help would be greatly appreciated.
