Need amp suggestions for Totem-based setup

Greetings,

I am building a mulit-channel system based around Totem speakers (Arros for mains, Mite-T for center and surrounds) plus a ACI Titan 2 sub. I have decided to go with a mid-level AV receiver (Denon 3802 or similar) as a pre/pro along with a multi-channel power amp. The Totems are a somewhat difficult load (4 ohms and not very efficient, the Arros are 86 db). Any amp suggestions, or features to look for, in the $1500 +/- range are greatly appreciated.

Thanks!
Dean
