dbpoweramp is a wonderful CD ripper, but there does not seem to be a way to select ripping speeds lower than the maximum. I'm using a Plextor 891SAF and it works very well giving rips at 20-30X speeds, except for one problem.
My collection includes some CDs older than 20 years and they seem to be more fragile. One broke during spin-up, probably destroying the drive as well. Maybe a 5X speed would keep these older discs intact.
