According to
this thread, Davehead is in Tampa with M60s. I don't believe he is a regular here on the forum.
When that situation arises, it is recommended you send a PM or email to Amie at Axiom and ask if she could put you in touch with him. Though I've never done this, I suspect she contacts him to see if he would be willing to demo his equipment, and then either gets back to you, or has him contact you if he's willing.
Give it a try. All she or he can say in no, and you're no worse off than you are now.
