I would thoroughly advocate the msb s200 power amp , I have used it with the vibe a great deal and have had diablos as you know and it would sound awesome . they are 6.5k s/h
if not then a modwright power amp may be just the ticket and I am sure BD audio will sort you a demo
ou might slip, you might slide, you might
Stumble and fall by the road side
But don't you ever let nobody drag your spirit down
Remember you're walking up to heaven
Don't let nobody turn you around
… Walk with the rich, walk with the poor
Learn from everyone, that's what life is for
And don't you let nobody drag your spirit down
