As you may have seen I have tested the 3 following drives:

LiteOn Ltd-163
Plextor Px-40ts
LiteOn Ltr-40125s

The results give me the following questions:

Each test has been performed twice for a certain speed, but they all show big differences compared to eachother. How is this possible? I would have expected more or less the same results... What factors might influence the reading of the test cd?

The Plextor was always considered as the king of DAE... This turns out to be a myth. How come that everybody was always mistaken? (The results are too bad to even consider this drive as a good DAE drive...

)

Some people say that with respect to the Plextor Px-40ts the newer generation cd-readers has taken over, for example the Ltd-163... I think that the results of my Ltd-163 are bad... It deals very bad with the 'blackened' part of the test cd. It deals pretty good with the scratches. But it reads errors near the end of the cd while there aren't any... Would a firmware upgrade improve results? (My current firmware GHOE, doesn't cache audio, while more recent firmware all cache audio...)

The LiteOn Ltr-40125s shows very good results on the 'blackened' part of the cd, almost all errors are corrected! But it performs very bad on the scratches... It loses track somehow... and from the beginning of the scratches untill the end of the cd it sees 1 big error...

So this drive is not good for reading scratched cds...

I would think that the drives would perform best on the slowest possible speed. The graphs show this is not the case. Anybody any idea why?

Should I test all possible speeds? As all the results show, the lowest speed is not the best. For the Plextor, it looks like 8sp is the best.

The spikes in the graph caused by the scratches are very high, higher then Andre's results. Did I make my scratches too deep? Is my testcd too difficult? But the spikes caused by the 'blackened' part are most of the time also a lot higher then Andre's result... is my black part 'too black'??? Should I make a new test cd?

So I was under the assumption that I had 3 good drives, but they all disappoint me... What do you think is my best drive?
