Writing curves
The Premium 2 introduces 48x CAV and 2x CLV writing over the original Premium. Interestingly the 48x CAV writing speed is not an extension of the existing 40x P-CAV speed. Instead an entirely new curve has been implemented.
The following graph shows the write transfer-rate curves for 23-52x and 21-48x CAV, 20-40x, 20-32x 20-24x P-CAV curves. - Posted:

FE/TE-Test comparison
Taiyo Yuden, Type 1, 700MB, 48x, as sold by Plextor
The Premium2 shows slightly higher Focus Error than the Premium.

FE/TE-Test comparison
Taiyo Yuden, Type 1, 700MB, 52x, as sold by Verbatim
Again the Premium2 shows quite a bit higher Focus Error than the Premium. Note that AFAIK Taiyo Yuden does not produce 52x media. So these are very likely 48x media only.

Again the Premium2 shows slightly higher Focus Error than the Premium but lower Tracking Error. Since these media are 40x only and the FE/TE-Test is done at 52x in the

I knew these were going to be bad even before I bought them. I just needed something bad to test and was wondering just how bad it would be.

FE/TE conclusions
On one hand it seems that my Premium 2 does focus slightly worse on the disc surfaces than my Premium does. On the other hand the Premium 2 sometimes seems to have a slight advantage in Tracking. Overall they are rather close together which we can take as an indication that the laser unit used in the Premium 2 is nothing revolutionary new. Any difference in favour of the Premium is small enough to be attributed to a more mature servo driving algorythm in the firmware. After all we must not forget that the Premium is a mature product while the Premium 2 is still in it's infancy (a fact that will surely also show clearly in further testing).
In comparison the laser unit of the PX-760 with it's "advanced intelligent tilt" capability shows a marked improvement, while a PX-716 would show about the same results as the Premium and Premium 2 (for results of the 716 see the generic CD-scans thread: http://club.cdfreaks.com/showthread.php?t=136562 ). - Posted:

Bad audio disc reading
Prince, The very best of Prince (Warner Bros. 8122742722)
"Bad" in this case does not mean the presence of a copy protection but rather a bad production quality of a pressed audio CD. The CD is otherwise in very good condition (no scratches etc.). This pressed this is of general low quality.
Premium: Can read this @22-52x but sometimes needs to slow down. Can read this without problems @18-40x (first scan)
Premium 2: Can read this @14-32x maximum (second scan)
PX-760: Can only read this at a maximum of 8x (no scan provided).

Bad audio disc reading
Donna Lewis, Now in a Minute (Atlantic 7567-82762-2)
"Bad" in this case does not mean the presence of a copy protection but rather a bad production quality of a pressed audio CD. The CD is otherwise in very good condition (no scratches etc.). This pressed disc has severe problems in the outer area.
Premium: Can read this with 20-48x up to the 28min mark, then slowdown to 4x (first scan)
Premium 2: Can read this with 20-48x up to the 34min mark, then slowdown to 4x (first scan)
PX-760: Can read this with 16-34x maximum (second scan provied).

Low speed FE/TE-Test comparison
Taiyo Yuden, Type 1, 700MB, 48x, as sold by Verbatim
FE/TE-Test run at 4x speed. (PTPXL doesn't offer to slow the Premium 2 to 2x in silent mode. As a side effect this also makes the results comparable.)
The Premium 2 shows slightly better Focus and Tracking Error than the Premium. The Premium 2 is on par with the PX-760 when it comes to tracking but the PX-760 takes the crown when it comes to focussing.

Premium: Disc can be written at the highest speed.

Again the Premium 2 shows slightly better Focus and Tracking Error than the Premium. The Premium especially shows more pronounced spikes in focus. The Premium 2 is slightly better in tracking than the PX-760 but the PX-760 takes the crown when it comes to focussing.

The Premium 2 shows better results than the Premium. FE/TE-Test thinks the Premium and PX-760 can't write this even @4x.

Again the Premium 2 shows better results than the Premium. The PX-760 looses in tracking and wins in focussing against the Premium 2.

Low speed FE/TE-Test conclusions
Compared to the high speed tests the Premium 2 beats the Premium regularly at low speed and even manages to beat the PX-760 in some cases (mostly in tracking). All this gives the indication that the Premium2 is indeed a drive that can handle / is spezicalized for low speeds as advertized. - Posted:

Taiyo Yuden, Type 1, 700MB, 52x, as sold by Verbatim
PoweRec: ON
GigaRec: OFF
AMQR: OFF
52x writing speed selected, slowdowns as per writing graph
Yuden CD-Rs are usually 48x certified only. The Premium usually rarely burns these at a full 52x. 1702 total C1 errors. Jitter-variations in the CAV-part of the burn.

PoweRec: ON
GigaRec: OFF
AMQR: OFF
40x writing speed selected, no slowdowns (52x speed offered by PoweRec but since these are archival-grade media with gold reflection layer I stuck with the certified maximum speed)
8807 total C1 errors. Very nice Jitter. Beta ist ok too.

MPO, Type 7, 700MB, 40x, as sold by EMTEC
PoweRec: ON
GigaRec: OFF
AMQR: ON
4x writing speed (pre-)selected, no slowdowns
21977 total C1 errors. Comparing the total amount of C1 errors to burns @40x and @2x it almost looks as if these media don't like AMQR. Very nice Beta. Beta has some downward spikes.
Below are C1/C2 and Beta/Jitter scans:
