Buchardt S400s


Just got these and would like some advice on a good amp to drive them.  The Outlaw 7220 seems like a good amp for the price.  My receiver is a Dennon 3400H.  Appreciate any suggestions.

+1 ghasley. My thoughts exactly. The 200 is rated at 80wpc into 8 ohms. Not seen a spec for 4ohms. 
I would go old school and try some adcom amps or Nad amps. I myself am rocking a B&K sonata 442 with 200w per channel.
