Squeezebox Duet DAC vs Rotel

I'm putting together a budget audio/home theater system where I have a Rotel RSX-1065 AV Receiver at the core. I'm also picking up a new Squeezebox Duet. My question: Should I use the Squeezebox internal DACs with RCA outs or should I use the Squeezebox coaxial digital out and use the Rotel's internal DACs?

Thanks
Brad
