The triple XXX sounds OK stock, but throw some EL34's in there and some JJecc83 pre amp tubes and you rocking, I love the tone of my XXX with the EL34's, its the only way to go on that head, also run it through a v30 loaded cab, that might be the ticket for you, I have a boss GE7 in the loop as well and it sounds amazing on the clean and dirty channels -
