Hi Slutz.
Here is my again optimized version you can compare to the original again It is pretty dam close after I did some more testing that you only will hear something when you listen very carefully.

If you do not own a good room treatment go and listen with good headphones.
The Lexi Unit sounds more 3D non resonant and more alive to me but the Plug In thing is not bad at all.
What I actually did to come there?
Here are the ingredients:
One Unit of Breverb = AUX 1
Two Units of Logic Audios Pitch Shifter = AUX 2
One Unit of UAD CS1 with Delay and Reflection Engine = AUX 3
One Altiverb MONO IR of Lexicon 960L AMB = AUX 4
One Altiverb Stereo IR of Lexicon 960L AMB = AUX 5
To show up every setup with every plug in it would be extending the scope here and I would have to type a very very long story.
You have the files you have some ears and some basics about room acoustics?
Go and try it for your self.
To be fair the Lexicon 960 L stereo Impulse is one out of the Halls of Fame IR package and not from Altiverb.
If you have questions ask me.....
