The heads must be a different thing to the combo then.

I think the combos are the OTB500 and an SP212 cab in the same box, nothing else.
I had the combo for a while, but it was faulty (speaker was buzzing slightly at all volumes - they did mention there was a problem with the entire combo line and thought of withdrawing them, but that hasn't seem to have happened) so Orange replaced it with the separate head and cab instead - I didn't notice any difference.
I really like mine - it breaks up quite early, but I play very lightly and don't have a problem with clean headroom. Keeping the gain low (at around 9 o clock), I find there is plenty of volume left on tap. Most of the time I go through the PA as well, but there hasn't been a problem in quite loud pub gigs with only a vocal PA either, with plenty of volume left.
