Budget amp for Dahlquist DQ-10's

I'm currently trying to make some use of a pair of old DQ-10's I've had sitting around for years. They're in good shape but I know they're probably dated technology. Anyway I'm on a bit of a budget and would like some suggestions on power amps that could handle these hungry speakers but could also be found used for under $1K. Aragon 4004', McCormack DNA-1, Bryston 4B? I'm not really sure if I'm on the right track. Any help would be greatly appreciated.
