Rick,Did you read this?
The revelation that digital interconnects and their direction can introduce large differences in measured jitter was quite a shock. The differences heard between digital interconnects—and in their directionality—have now been substantiated by measurement.

Quote from Stereophile article.
Conclusions
There is now no question that jitter in CD transports and digital interfaces affects digital audio sound quality. Not only do different transports and interfaces sound different, they produce varying amounts of jitter and have their own "jitter signatures," seen in the jitter's spectral distribution.Moreover, we can see that transport jitter goes right through the digital processor's input receiver (even the Crystal CS8412) and affects the amount of jitter at the DAC's word clock—the point where jitter makes an audible difference. If the word-clock timing is different, the sound will be different.

Although the CD-transport measurements presented here are fascinating, it is impossible to draw conclusions about how a transport will sound solely by looking at its jitter measurements. Based on the measurements and listening impressions of the Audio Alchemy DTI, we can confidently conclude that the jitter differences the DTI imposes on both high- and low-jitter sources are easily audible, and that lower jitter always correlates to better sound. But when examining the jitter performance of other transports, a direct correlation is less clear.
