I watched some of the scenes the Sonnie posted and some scenes the LLT had more information then the IB, I can hear more sounds when played the LLT, we switch back and fourth during the same scene and you can hear other things that you couldn't with the IB

My son was switching amps during the scene and even him said that the LLT sounded better.
LORT Return of the King, mount Doom, chap 53 definitely there was more sounds when we played the LLT, this is not on all the scenes some scenes it was hard to tell the difference.
MI III, standby to go live and phoenix get to the LZ chap 3, the LLT outperform the IB

on this scene you can feel the blades going right by your head, it just sounded and felt better with the LLT
Open Range the gun shots, again the LLT move my pants more then the IB, specially with the double barrel shotgun
I dint hear any port noise or anything weird coming from the LLT, or the IB,........... I did heard something coming from the IB when we played a BASS CD that I used at work on car stereos, both of the amps set the same way and no EQ , it sounded like the IB bottom out,( made a clack noise ) the LLT did not made the noise!
The scene "Irene" from Black hawk down, its louder with the LLT and you can feel it more
I'm not very good explaining things

so if there is something the you want o need to hear............. I guess you better come on down and tested yourself!!
