I burn CD's on my computer, which sports a DVD drive; and I consider my rig to be fairly hi resolution. I've noted fairly consistently that on MOST main-stram labels, the sound quality increases with the burned copy; and with something like an XRCD and other hi-end recordings, it decreases some. With the XRCD's in particular, the literature talks about how they go thru all this trouble to reduce jitter in their final product. This suggest to me that it may well be a jitter thing, since most of the purist labels use higher quality converters (ADC's and DAC's). Of course, this is only speculation on my behalf.
In either case, the differences are not usually enormus, and in some cases a difference is very difficult to detect. I always end up with a copy that I'm happy with....I am not going to dubb my collection, and I'm not going to buy something that I can copy.
Also, when dubbing the more Hi-end labels; using Gold blanks closes the gap even more, sometimes making them indistinguishable. These have come down to under $3.00/pc
