As stated here, I've tested my drives with the DAE quality test from the EAC homepage.

Further explanations about the test procedure can be found here, so here are the facts about the PX-716A:

Conclusion
The drive never had to slow down extremely (like some the other Plextor drives tested). No problems with the extraction process at all.
The PX-716A reached the best results at 24x (based on the "Total Test Results" numbers). Like some other tested Plextor drives, the results got slightly worse when lowering the speed to 4x or 8x.

So regarding DAE of Plextor drives, the PX-716A seems to line up between the PX-708A (wich produced the best overall results) and the PX-755A (worst results).

I feel it worth mentioning that the speed results don't agree with my experiences ripping damaged/defective discs. I have found that ripping with this drive produces more accurate (or at least more consistent results). This also coincides with the fact that PlexTools reduces extraction speed when it detects errors.
