I am never a fan of SACD myself even though I might have about 10 SACDs in my library. I am sure the C-5XE's redbook playback capability is much better than the C-7XE. Many internal components are different in the two models and I doubt those components are for SACD only.
For most high end players, their balanced output is always better. I do have faith that the C-5XE's single-ended output is still better than a cheaper player's single-ended output. Just that you won't see the full potential of the Ayre until you go balanced.
You should get the best player you can afford and as I said, this may be your last player. You may upgrade your downstream components later on and don't need the x-over at all. Good luck.
