I use a PX-760A for ripping my CD collection, using dBpowerAMP 12.1. I have noticed two strange things with the PX-760A.
1) Most of the time, the read speed is only 8X. I occasionally get 18X. It does not seem to depend on the CD (the same CD sometimes reads fast during testing). Googling the topic seems to indicate that this is really a feature of the firmware, which reads the TOC at beginning and end and gets very conservative on speed if there is any difference - and this is done when you insert the CD, so a single speck of dust will reduce rip speed until the CD is removed
2) dBpowerAMP does not read ISRC and UPC from this drive. It does read them on my other CD drive (Philips 8881, which does not handle C2 errors...). The drive advertises ISRC/UPC reading, dBpowerAMP reports it as supporting ISRC/UPC. The strange thing is that the PX-760A does read the ISRC/UPC using two other programs (PlexTools, and Tau Analyzer), so it may be a bug in dBpowerAMP - or the support in the drive may be half-baked, and DBA uses one of the unimplemented features of the drive, while the other two programs use a different subset of the API...
I think issue (1) is purely a 'feature' of the drive on which DBA has no control whatsoever. Issue (2) may be (partly) a DBA bug.
Side question: DBA keeps a cache of recently seen CDs. Is there a simple way to clear this cache [e.g. to check out the ISRC issue ...].
Thanks,
