It can output to an amplifier. It uses a special adapter in order to get the subwoofer out. According to their diagram (bottom right going from HDP to amplifier).
"Subwoofer connection - a RCA male to two RCA female AudioQuest adapter can be used to provide extra connection to subwoofer."
I'm still wondering if the subwoofer outlet is a good option because it might be the wrong kind of double amplification. You do need to shoot Fried an email over at Violectric and ask him about it. Try to send him the spec info for the Nuforce Icon in case he is not familiar with it.
