I have the N802s and an HTM1 up front in my HT (SCM8s for surrounds).
I use an AMP5 for the three front speakers, bi-amping the N802s. I have been very happy with the results.
I can cleanly drive the speakers with zero distortion at volumes far larger than I would ever listen to for an extended period of time.
NOTE: I originally had the AMP 5 running all 5 channels, as my L/R were originally Naut 804s. When I made the jump to the Naut 802s, the AMP5 was a weak link. After bi-amping, all is good. I point this out because a HPA3 may also provide similar results, and allow you to have similar amplification to your front 3 channels.
