16. Conclusion

Passing to the ABEX TCD-721R test discs, here things would be much harder to accomplish. Using the ABEX TCD-721R with Nero CD-DVD Speed gives us some first results.

Making a summary of the above tests, it shows that the non PureRead 4+ function seems to produce higher C2 Accuracy and "Quality" Score compared with the PureRead 4+ mode enabled. As it seems the drive with the Perfect/Master mode "misses" to report many C2 errors so that gives the high error rates with such "bad/scratched" media.

ABEX TCD-721R Nero CD-DVD Speed Advanced DAE Tests
	C2 Accuracy	Quality Score
No PureRead 4+	81.68%	77.1
PureRead 4+ Perfect mode	-	-
PureRead 4+Master Mode	80.18%	79.0

After this test, we decided to perform real life tests, comparing the rips of the Abex TCD-714 vs Abex TCD-721R vs EAC Burst/Secure mode.

All wav rips compared with the DeltaWare software that give us if the tracks are identical or not and how much chance there is to hear audible noise/hiss/skips, especially above -160dbFS score. So keep in mind the higher the RMS score is the better (less chance to hear problems).

The Pioneer with the harder to read Abex 721R disc, seems to work good with PureRead 4+ Master Mode compared with the EAC Burst (No PureRead4+), in some tracks in others didnt.Note that the above results only apply for the R sound channel, while comparing also the L channel would introduce different results (limitation of the compare software). Note that the higher the RMS value is (towards 0) the higher the possibility you will hear an audible error/hiss/pause/etc.
