Recording S/PDIF & Analog at the same time

Hi - This is a question for you folks that have Pods or J-Stations. I have a J-Station. I also have an M-Audio Audiophile 2496 sound card. To date, I have only been doing analog recording of the J-Station. The sound quality has been just fine that way. However; I am realizing that if I used the S/PDIF output from my J-Station into my AP2496 S/PDIF input, I could be recording a couple of analog channels at the same time. For example, that way I could record guitar & vocals at the same time.

I see that M-Audio requires that when the AP2496 is inputing S/PDIF that the external S/PDIF device has to act as the master clock and thus sets the sample rate for S/PDIF & any analog being recorded at the same time. The J-Station S/PDIF sample rate is 44.1 Khz, which is just fine for the analog audio sampling that I want to do at the same time.

My question is : is there any down side to letting my J-Station control the sample rate? Does that result in any degradation of the AtoD quality of the analog audio I am recording at the same time? Also, if I record more tracks later, from analog-only sources, and use the AP2496 as the sample clock master, will there be any incompatibilities with the tracks? BTW - I am using SONAR 3.

This should all work. I'm just leery of compromising my AtoD audio quality.

Any advice would be greatly appreciated.
