I think this video really demonstrates the different voicings and strengths of these two amps. The 800 really wants the gain up higher- that is where the sound fills out. When it is kept lower like this video, the sound is thinner with less meat to it. Personally, this is a situation where I'd take the Origin for this classic rock style. But for a more aggressive rock tone, the 800 wins all day. Horses for courses, as they say.
