Some reclocking solutions are more effective than others. If the G91 reclocks perfectly then there would be no difference between the CD player and the Airport Express, assuming jitter is the only problem.

The point is, a perfect lossless rip of a CD, served digitally over an error-free cable *should* sound better than any CD transport available. If it doesn't, it's not the fault of the concept, but rather the implementation.
