Recent drives are somewhat trash for the enthusiasts of digital audio extraction, because recent drives lack near always of overreading into the lead-out, and sometimes of overreading into the first pregap.
Without taking into account real Plextor drives, my old GCE-8526B LG-Hitachi CD writer is just fine for PSX: reads finely without workarounds no longer allowed the last sector of data tracks of no EDC discs with audio tracks and can overread into the first pregap AND lead-out using EAC, so for any +2 PSX disc is just fine. A -647 disc which would lose potentially audio samples due to negative combined (-641 samples for a +2 discs)? Just rip the first audio audio track in a +667 drive and solved.
Tha main problem with current conventional drives is the lack of overreading into the lead-out (however, audio trap disc method acts as workaround to rescue the lost audio samples when supported). Tipically, conventional drives won't read into the lead-out at all, so the risk of losing audio samples (especially for +2 discs and +667 drives) does exist and you cannot match certain DB entries due to that.
Examples of entries you cannot match with a +667 drive:
For discs without audio tracks... near every modern drive is fine.
