I would still strongly recommend the Dread. The Parasound Halo is a powerhouse, but not nearly as musical to my ears. Your speakers will play loud, but the Dread will more than hold it's own in that dept too. I've just never heard each individual instrument stand out with a multi-channel amp as I have the Dread. There are some amps I've heard that can match in on width of soundstage, but very few on depth. Very clean from top to bottom. Just amazing for both music & movies.
Good luck on your choice.
