I agree with Chazzbo - rather than "weak" link look for a variation on your approach to reproducing music. Think sonic change rather that weakness.
I see your all SS rig and think tube pre-amp or as someone has suggested a turntable. Or perhaps a passive preamp. Maybe a CD player that has been noted for its smoothness and edge free reproduction. Look for changes to make your system a bit more forgiving of bad recordings and warm up the midrange.
