Hmm, I thought I had read a post from Cliff that stated that one of the things that made the IR and the amp respond the best together was to adjust the speaker resonance in the amp section to match the speaker type. Perhaps someone else wrote and I mistakenly attributed to Cliff. Certainly don't want to undertake an exercise in futility....lord knows I have plenty of this as it is!
Yes, I said that, but it's still nitpicking.
