Re: SPDIF to AES on SC48
One more note on sample rate conversion (SRC)...
SRC can of course be used to convert from one sample rate to another (e.g., 48k to 96k, or vice versa), but it's also useful even when the two devices are at the same sample rate. Even though two digital devices operate at the same sample rate, there is no guarantee that their digital clocks are in perfect synch. In fact, they almost never are. When devices are connected at the same sample rate but their clocks are out of synch you will hear audio, but with periodic clicks and pops. One approach to synching the digital clocks between devices is to use a physical clock connection, like a word clock. SRC - even if it's not changing the sample rate - mitigates the need for the word clock connection by re-synchronizing the incoming audio at the receiving end. The net result is that the two devices are operating at the same sample rate, and even though their digital clocks may be out of synch with each other the resulting audio is free of clicks and pops.

Re: SPDIF to AES on SC48
I find myself using the digital I/O of the VENUE's quite regularly, with no problems or issues thus far (fingers crossed). MAXX- I raised an eyebrow when I read your first post...it kind of scared me...knowing the impedance difference and level differences between AES and S/PDIF. Not something I would have tried myself...without using a converter between the two.
Let us know if you find a working solution. I'm with Sheldon...I think if you put a S/PDIF to AES converter in line, everything will work just fine. If not, I'd look to getting a true AES output CD deck or going analog. I wish the iPod's had a S/PDIF or AES output =)
