Ahh, its nice to be back listening to you folks again, its been a while since my last visit.
I drive all my Axioms (front stage M80s and VP180) with a NAD T785HD and haven't ran into any issues at all. This is in a fairly large space and I can crank it to ear bleed levels...the NAD is more then capable.
