ARC 100.2 Enough power for Proac 3.8

I am looking for a power amp with plenty of grunt to drive a pair of Proac 3.8's.
Currently they are being driven with an Ayre V-5x which has been kindly lent to me by a friend. It sounds gorgeous by the way, but could use a bit more "slam" in the bottom end. It's damn close to perfect though.
The catch is that I can't afford one of those beasts and have read good things about the 100.2 from ARC. Could this be the beast I am looking for or do I need more power. The Ayre is 150watts and the ARC is 100watts but apparently belies it's output rating. A VT100mkII is also tempting but I'm not so sure about the tube approach.
Any other suggestions would be appreciated.
