Happy users of SPDIF in Lampizator Big 7's?

I am considering moving to a Lampi Big 7, but I have one pretty important reservation. I plan to have all of my DAC's in the house fed via renderers that draw on a NAS, because I really don't want a computer in my listening rooms anymore, so going to an ethernet feed off of a remote NAS is very appealing. I was anticipating using SPDIF as the inputs on the DAC's, but I read Jafox's disappointing experience using the SPDIF on his Big 6 versus the USB input, and that really gives me pause about a Lampi in this scheme.

So, any happy Lampi Big 7 users that have compared USB to SPDIF and find it just fine?
