What could he have raised with preflop? King of diamonds and what? by the river we learn the J is out, you had the T, and the 9 and 7 are in the flop with the A. Did he come in with A Kd and then show that much aggression all the way through? I feel you're pretty safe, I put him on KKd or AA.

I'd normally say slow down, but the likelihood of him having KXs with that raise preflop seems really weak.
