I have another post on using BLER. But I found that the BLER test needs be run as slow as the CDROM will read. I have used 4X and 10X, both giving close to identical results (because the 10X actually runs 4-6X for most of the scan). When I ran read scans at 48X, the scan found C1 and C2 errors in the thousands. The same disc read under 20 C1 errors (max) with an average under 1 C1 (entire disc) and no C2 errors when the scan speed was 4-6X.
So it stands to reason that when copying, the slower the read the better. I am not sure if CDROMs have a playback speed control, but I think there is dedicated software to do this in a utility. Most DVD/CDROMs in computers these days want to run at 48X, and they will be correcting for a lot of read errors.
Using "secure" ripping software like dBpoweramp will also assure a "bit perfect" rip of copy of your CD. They use a file compare system that compares your ripped file with an online database of others who have ripped the same album. If the database has two or more identical entries, then dBpoweramp claims the bit error in the copy is essentially zero. If you are also using this software with a CDROM that has C2 error detection support, then there are further assurances that your copy is exact.
Regarding the use of "PCs" to manipulate and playback high end music files, check out "computeraudiophile.com" They have also found that there is a lot more than meets they eye when building a music server.
