Just to add my 2 cents - I've also been struggling with getting the attack immediacy in the power amp + cab setting (I'm using a Hypex NC252MP Class D amp, which was a dramatic improvement over the SD Powerstage 170 and the Matrix GT1000FX in my case). Compared to the real amp the initial attack has less definition and seems to be less pronounced in the higher mids with an excessive amount of bass + lower mids which off course can be cut at the cost of some liveliness.
