Guitar Speaker IRs - one step better?

[jbraner]

Hi,
Is anybody here using Neutron Audio Quantum Speaker impulses instead of IRs?

They use NAM profiles instead of IRs.

I've been playing around with these and I do like them. I don't see too many other mentions about them - except in their Facebook group.
My current "go to" speaker cabs are Two Notes DynIR. They're very good but they're basically "normal" IRs (just a whole lot of them organised so you only have to move the mics around to change the sound). I know that IRs are "static" (snapshots) of a speaker response and there must be better ways to make "dynamic" "non linear" responses to a signal played through a guitar speaker. I'm using all the buzzwords, but hopefully you know what I mean.

I'm definitely interested in what's the next step after IRs - is there anything else to be looking at?
Anyone else tried the Quantum Speaker profiles?
