Amati and Mac???

I have a mcd/mda 1000 source driving a set of mac 501's
directly via balanced transparent audio ref cables. Any idea how these would mate with a set of sonus faber amati's. I like warm, relaxed, forgiving sound as all
sources will be digital via the mda (which is excellent).
I can not use tubes as I have very young children who touch everything and the system is in our main living room.

Thanks,
Theodore
