toslink connection from streamer as source

[RLim]

Hi 
I am considering buy a music streamer / server.
e.g. lumin u1, innous sense or aurender n20

does anyone has any experience with a pair of phantom1 with any of the above music servers/streamer?
i intend to connect them via toslink, some of these streamer has higher bit rates than the phantom's optical in specs, not sure if it would works correctly.

would appreciate any experience sharing on music servers that work well with the phantoms
