I've been working on some new methods of measuring and comparing amps the last couple weeks and came up with an improved matching technique. The crux of it all is that the default "CF Hardness" value is slightly low for a typical amp.
If you are using an amp model with a cathode follower, i.e. Marshall, Friedman, Bogner, Rectos, Diezel, etc., you may want to increase the CF Hardness parameter to around 7.5. It varies with the type and brand of tube (12AX7A vs. ECC83, Mullard vs. JJ, etc.) but 7.5 is roughly the mean.
It's subtle but you get a little bit more sizzle. Of course your ears are the most important factor and if you like it lower, then by all means, set it lower.
