I'm not dreaming - these are great CD copies
Can you really improve the quality of music from a red book CD by simply copying to some other format? No. Data on a red book CD is stored as a cda file. As such, copying a cda file results in the same cda file being copied elsewhere. Ripping a cd on the other hand can result in a change of format, such as wav. Once in an editable format such as wav, the file can be reworked in the digital domain and as such can be improved (subjective) relative to its parent source file. |
I thought Audioengr (Steve) had commented about this in another thread some time ago. My recollection is he said copying the CD onto a CD-R eliminated one contributor to jitter (I don't believe it eliminates jitter in any absolute sense). If I recall correctly (and that ain’t anything to bet on) there’s less (imprecision?) in how the dye-based copy is read vs how the laser beam falls on the "pits" making up the stamped CD’s information. |
There is a review (that I can't locate) that explained how a laser reads the physical pits and grooves of a CD. It's being done in an analog fashion ( a mechanical process) which then had to be processed into the digital domain. With the laser just reading a painted pit and groove, there is less chance of error. Physical pits and grooves aren't as well done as they should be when stamped. A painted one can be very precise, comparatively. All the best, Nonoise |

There’s a lot more laser error correction goes on in a burnt cd compared to a stamped retail CD see the "pits" the laser has to read.
