Hope Mike doesn't mind, but I am posting his DM response to this question. Posting here just for reference so others can see:
"I have been trying to think of any changes made to the Jag with LFM vs the Jag 2000. The more I think about it, the more I am pretty sure that there was little if any change other than working on the integration with the LFM. So, realistically, I don't think there will be much of a a change in what is coming out of the Jags themselves. The main advantages of the LFM were of course headroom and being able to precisely adjust and tweak the LFM response to match the Jags and the room. Hope this answers your question!"
