MacBook Pro to EMM XDS1


For owners of this fine EMM product, what's the preferred way to get music from the computer to the DAC? I've been using Toslink, but I'm wondering if there is a better option. Both are less than one year old.

The Weiss INT202 is excellent but expensive. The best interface I have used so far.
Only downsides to me are:
a. it's not compatible with integer mode with Snow Leopard and Pure Music
b. there is no way to encode DSD audio via this interface which is a shame since the XDS1 uses a native DSD DAC>
