i recently bought an arcam alpha 9 on agon for a couple of hundred bucks and i'm really happy with it--rated at 65w/ch, but it roars w/lots of transparency. it's predecessors were a nad 325 (lots of oomph, but somewhat unrefined) and an 85w denon integrated (not much high end detail). i have also auditioned your onkyo 955 but didn't quite grasp the accolades reaped upon it--it was okay, but as you put it, sorta laid back, not dynamic and forward like the arcam or nad.
all that said, i think you'd be well served with an arcam; alternatively you can find used rega or creek in the same price range; any of these will provide a considerable level of refinement, esp. since you don't need a ton of power.
