DAE quality report on Samsung SE-S224Q

I would worry about some of the turtle wax getting onto the laser lens. OTOH there are reports that people who applied armor all to their discs caused serious damage to both the discs and the lens.

Armor All never "sets", always remains a liquid,  and would be subject to fling.  Look in the wheelwell of any vehicle which has had Armor All applied to the tires for proof.
Carnauba/beeswax combos, on the other hand, form a cross-linked solid polymer as the solvent evaporates and would be highly resistant to fling.  Outside actual collision between the disc and the lens you have nothing to worry about - and if that situation arises you have larger problems. 

All that being said - the direction any material would be flung from a spinning CD is perpendicular to the direction the lens lies in relation to the disc.
Creature of habit.

Wait a minute...

Looking at your first set of results, ripping at higher speeds with the Samsung produced more errors whereas in your second set, higher speeds produced fewer errors.

Yes, curious, isn´t it? That´s why I have the doubts in the total error count. Without the second test I wouldn´t have seen it. I´ve tried to think about the reasons in the last hours after talking to my friend. So far I came up with the following explanation:

1. first test: 4 rips with every speed (40x 40x 40x 40x) - the measurments you see here are always from the second of those four rips. I made the rips without pause, maybe a temperature influence. What I still find puzzling though is that the total error count from those 4 rips done in a row was relatively consistent (about 300-900 errors at the highest speed with a total error count of around 200.000) - as was the final outcome of every test. I´ve had fluctuations like +/- 0.2 between every one of the four rips for every speed.
2. second test: 2 rips with three speeds and two drives - after the first rip with one drive I didn´t do a second with the same afterwards, instead I used the other drive to make a rip. took about 2-8 minutes, depending on the speed. since I left each of the drives open while the other was ripping they should have had time to cool down.

The samsung obviously has problems with slower speeds the more severe the error gets (the second disc was much worse in terms of visible error). Also, the Samsung seems to be quite unreliable when it comes to C2 error hiding which I think is the exact reason why it is affected by the green marker so much. The singular point that was consistent with every test I have done (first & second) was that the green marker changed the outcome of the test with the already mentionend tendency (except for the LG). Still, this tendency is so small and that´s also why I said that one shouldn´t draw general conclusions too fast. I´m afraid that spoon is right about doing the test again. Furthermore, that´s why my friend came up with this painstaking test routine I mentionend - he simply 'accused' the Samsung as being an unreliable instrument for testing - he may have a point there. I could bite myself in the a** that I didn´t came up with the idea of testing the LG sooner. Would be interesting to see how it would hold up with the first test disc. Maybe I´ll make a quick test in a few minutes...

You're using the past tense, but lo! :

Are you sure you want to help advertise?  For 69 cents I can probably find a black marker that will work (or not work) every bit as well.



I'm not worried; I kinda doubt HA is the market for that product. 

(But just in case, I hereby implore Cavaille: DON'T SUCCUMB.)

Sorry to interrupt your discussion here, but...

However I ran into a few problems. C2extract.exe couldn´t find my drive - perhaps because it is an external USB drive.


I had the same problem when DAE-testing my drives with the same method. Have you tried to put a wnaspi32.dll in the directory where you started c2extract.exe? That worked for me...

No need to be sorry. Thanks for the tip. I did not try it yet - it would however show if the drive can do a proper C2 error flagging if I understood it right.

I wouldn´t trust a five year old LG drive even if it would be the only drive I´ve got.
Can you say why?

This might be a bit revealing:

P.S.: I still will not use the LG drive for ripping my music - its sound is just too bad, it changes the sound too much towards mellow and cloudy. With pristine CDs my Samsung still is way superior in terms of sound quality. That I obviously couldn´t write over at hydrogenaudio.org since it is forbidden about sound without a DBT (double-blind-test).

It´s all true - I wrote that. I´ve always admitted that I like staying on both sides (subjective/objective). But it still doesn´t belong here. Furthermore I personally don´t think that this is revealing since my signature here has depicted the address of the other forum for quite some time and if you look at my other posts at the "HiFi Wonderland" you´ll find many more claims without DBT.

I myself would find it much more interesting how I simplified the whole process in the description and how imprecise I was technically.

I guess I'd like to set you straight on your erroneous and ill-founded belief that two rips from different drives that produce the same CRC are not going to sound the same.  If you suspect that the files are different and the CRCs are the same because of a collision (to say this is extremely unlikely is a huge understatement), you can easily do a sample by sample comparison.

And not only that, yes there is a 1 in 4 billion chance of a collision on CRC, but for all 10 tracks of a CD to have a collision...

Sorry for abusing this topic if I am, but I can't find any reviews that test DAE qualities of the Samsung SE-S084B drive. This topic shows the S224Q seems an excellent choice for my purposes (fast, flexible and especially quality DAE), but is there anybody who has experience with the S084B? Or has resources with more information?

Any help would be greatly appreciated.
