Help !! Mbox +Mini Me latency issue
 

I am thinking of putting a portable system together for overdub purposes . I have been looking at the mini me as option for a mic pre a/d converter ,then s/pdif out to the mbox.I am led to believe that there will be latency issues when monitoring with using the s/pdif input of the mbox PT LE and the Mini Me. Can anyone shine some light on this subject ,or suggest how to get around it.
cheers
