As you can see from my posts here http://club.cdfreaks.com/showthread.php?t=209975 I’ve not had much luck with this 20A1S so far. The only half decent scans are of discs burnt with my (now dead) NEC3500AG. I’ve only got Infiniti MCC02RG20 -R and YUDEN000T03 +R discs at the moment, so I can’t see what results I’d get with Verbatims (which is what I usually buy).
I got my brother a 18A1P a few months ago and he’s not been getting great burns either and one of the reasons why I bought the 20A1S was that my having a similar drive might be useful in finding out what discs/settings these Liteon drives work best with. So if anyone’s got any suggestions I’d be grateful (I guess updating my firmware will be the first one, although I’m skeptical as to whether that will make much difference). I’m still able to exchange my drive for another make but it’s too late for my brother.
