Alas, Tyranny
Sounds good to me, I'd pay them the extra 10 quid and wish them Godspeed! (and again, I think a big part of the Mesa cab sound is that they're all 8-ohm V30s wired to 8 ohms in mono, so that'd be my vote as well)
Does the impedance of the speakers/cabinet really make any difference in the sound?
