This will add quite a bit of time to the project since I have to learn a new tool from scratch. I hear that Eagle has a steep learning curve... :( Any links to some good tutorials are appreciated.

Don't bother. Use the tool that you know. Spend the time on making the project work, not learning a new tool just for this.
Few people will complain that the original files are in Altium, let them re-do it in eagle if they are keen enough, a shield is not that big of a circuit.

Thanks for your input Dave. Unfortunately, I do not own an Altium license myself, my employer does. The price is prohibitive for a single personal license at the moment.

Yes. It is a fairly simple part to implement with low parts count. This makes it attractive for this project as I can keep the cost low.

If you jump over at DiyAudio, there are dozens of those things, with topics that have more than 1800 pages, lots of ideas, pcb's, clocks, buffers, adc's and dac boards, at least for audio there are lots of options, and for example the minidsp guys have affordable pcb's with a lot of software to generate the filter coefficients.
Take a look at them/maybe you already know all this :-[

The MiniDSP guys have build a (closed source) business around boxes with these ICs.

Hi senso,
Yes, I've had a look at the miniDSP stuff which is unfortunately all proprietary (closed) has Marco mentioned already.
Thanks,
Mike
