A couple of thoughts:
1) The marantz transport could be the limiting factor if the 360S is not reclocking the digital input. Does the 360s reclock the digital input to remove jitter ? The marantz player probably does not have a very good clock internally. Mind you, it seems unacceptable to me that the 360, costing over $3k doesn't reclock the input !
2) People overemphasize the differences in digital. My own experiences are that moving from a $400 player to a $2000 player do not give the same leap in performance as that amount would do in terms of speakers or amplifiers.
