How come there is no thread on the RealityCheck?

Based upon the rewritten CD's that I have tried, I believe it is just jitter in the pits of the original. If the data is transferred to a computer hard disk and then rewritten by a burner with a precision low-jitter clock and clean power, such as batteries, and the copy is made at low speed to get more accurate pit shapes, then the copy should be significantly better than the original. Makes perfect technical sense to me.

This makes no sense to me either. Copies from the hard-disk should be every bit as good or better than ones from the original CD.

This prompts what is perhaps a silly question, but here it is. If one burns a black CD on a laptop computer running on battery power, and the copy is made at a low speed, would it then follow that this burned CD would conceivably be better than the original, notwithstanding the inferior clock on the computer?

Audioengr, your lower jitter theory is a reasonable hypothesis, but if jitter from reading the disc is the culprit, this then begs the question of why, given the low cost of memory and computing power, doesn't every player above the entry level read and re-clock the data to the dac thereby eliminating this variable from the equation? This seems like a much more elegant solution to the problem than the meticulous cleaning of discs and then re-writing to a blank CD which has a limited lifetime.

There are numerous high end players that do re-clock the data. I wonder if this re-writing process has any audible effect on their playback?

I am also curious why I never see any test data on the bit stream coming from a transport before and after such treatments are applied. With the right equipment it would be very easy to analyze this stream of bits and see what if any differences there are. It might not tell us what it would sound like but at least it would demonstrate that there are differences.

Herman, great thoughts. Were I to have the equipment I would try it.

Audioengr, I had two cds that would no longer play because of scratches. I did succeed in copying them using my computer. When I got the RealityCheck, I tried to copy one from the original. It failed partially through the burning. I then copied the copy. It was far superior. Recently I recopied using my computer and one of the black cdrs supplied by George. I then copied it using the RealityCheck at home it was further improved. I found it somewhat better than the RC copy using the silver cdr.
