recently got the LPS-1 for use with MR/FMC config with Mac Mini server and Schitt Multibit BiFrost DAC - got Wireworld Starlight CAT8 ethernet cables to the MR and Mac but while the cables snap into the downstream FMC and MR, it fits loosely (no snap) in the Mac Mini (2013) - this a common problem? any other quality/shielded cable alternatives?
