I just read some information where Phillips acknowledges that CDR's are infiror to pressed cd's, even when the information is bit to bit identical. They have specs to support it but they are not sure why. Check out this web site www.mrichter.com and go to Audio Losses. If you use MSN you go to #4 Audio Losses. Otherwise you may need go through his home page a navigate around. Well, this certainly adds fuel to the fire, huh?
