the black marker technique is not necessarily a good thing. Certainly a difference can be heard when playing a 'blacklined' disc vs. not lined. I didn't believe it either, but I actually tried it before posting opines that it simply cannot work; it does work. However I discovered that the marker technique actually caused changes in the sound that I didn't like, so I removed the marker with alcohol and the sound reverted to its' original state.
Same result for the Auric Illuminator product. It certainly does change the sound, but not necessarily in a good way. I'm glad that the product is also removeable.
You have to remember that the ones/zeros are not digitally encoded, they are contained within an analog modulated carrier envelope which is detected via laser pickup & decoded back into digital. Certainly there are numerous causes of bit error degradation along this circuitous path.
