@Whatthe, congrats on your Q5's! If you're running the big SS-102 or SM-102's your Q5's will have enough juice to properly control them. Because the Q5's are more neutral, I would (personally) lean toward the SS-102 which sounds a bit warmer than the mono's, but that's a matter of personal taste.
In general, Vitus pairs extremely well with Magico & is one of the few amps which makes the Q series sing. I've also heard good things about The Gryphon, Pass XS series & CJ Art/Gat amps.
