The 1.6 Maggies - any thoughts on best amp?

Bought the Maggies last summer. Like them a lot, still having fun with positioning them. Have a Rogue 66 tube pre-amp (like tubes) and a SS 200 watt Acurus power amp. The amp's got enough power it seems to drive them but I haven't really experimented with any other amps. Thought about a tube amp. Looking for thoughts/comments or suggestions. Thanx
