MacBook Pro to EMM XDS1

Yes, the XDS1 is a brilliant machine. If you don't require the last mile of neutrality, I also recommend the Playback MPS5. I've heard it in my system and it sounds beautiful too. Very similar to the XDS1 but perhaps a bit more oomph in the mid bass which is a nice characteristic. For the price though, it's a relative bargain compared to the XDS1.

I use a FW-AES like Weiss INT202

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>

As can be inferred from my post, No.

I did ask EMM before and they said pretty much the same thing. The only way to get USB DSD is to get their USB DACs, i.e. MA-1 and DAC2X. But if you already have the XDS1, you are as they say S-O-L.

If only they saw fit to include a DSD USB input :(
