A question about PX760A review

I am considering to get px760a and investigating several reviews.
After reading cdfreaks review about px760a, I have a question.
The review contains some cdspeed quality scan and the scan shows some single pif spikes above 4.
Are those spikes ignorable ?
I have never seen those spikes in other machine, ex LG, Pioneer etc.
Frankly speaking, I bought a PX755A and found that spike and refunded it.

Is that spike OK ?

I ask you some advice for buying PX760A.
Please help me.


The rule is PIF<=4. So basically everything above that is bad. (Notice Plextor drives with PlexTools reports PIF per 1ecc as it should be, whereas other drives/software do so per 8ecc which makes values >4 ‘normal’). However it’s important to understand that all these scans are done with uncalibrated consumer equipment and therefore are to be taken with a grain of salt. It means that the results are not accurate but only and indication. As a consequence a fixed limit kind of looses it’s significance since you cannot accurately determine whether you are above or below.

To give you some example: I’ve never seen a result like this http://club.cdfreaks.com/showpost.php?p=1496377&postcount=40 cause a problem in practical everyday use. Results like here however http://club.cdfreaks.com/showpost.php?p=1470023&postcount=29 would make me worry (and even the smaller spike alone would suffice).

You’ll notice that in the second example, while there being a colossal spike of PIF the content remains perfectly readable for the drive used. So passing those limits only means that SOME drive might not be able to read it anymore, whereas a respected limit SHOULD guarantee universal readability. However even the respecting of those limits sometimes causes problems as some cheap drives cannot even cope with ‘regular’ discs.

Here’s some further stuff worth reading:
