Randuin's Omen (or Warden's Mail on its own is nice). Banshee's Veil is great. Period. Sunfire Cape if you for some reason want the passive damage on Xin, Force of Nature if you don't need the health from BV.

Wit's End and Malady might work well with Xin, what with the attack speed on them, though they would be quite situational.

Like I said before, you don't need to build the big items right away. An early / mid game Chain Vest + Negatron Cloak will do a lot for your survivability.
