I think it`s realism, as although I rarely use my full gigging rig I`ve done pretty much the same. My mind tells me that my ABM600 and matching 210 & 410 cabs was better - and it was sound-wise, however my ABM600 with two ABM PRO NEO 210s is better for my needs, and that`s the important thing. Even better is that for one of my bands the RM500 fits the sound more than the ABM600 does.
