When George Lucas, who can afford any amp in the world, chooses Parasound to be used at Skywalker Ranch, that should tell you something. Now whether Mickey decides to keep Parasound at the ranch is another story. We'll have to wait and see.
Seriously, the Halos are great amps. But it sounds like your hoping to find that one person who has owned both, the ID brand Odyssey and a Parasound and who has compared them. I would think findiing that rare person will be tough and it may end up being you. So if you buy both amps and do the comparison, let us know which one you end up keeping. I'll bet it will be the Halo. Happy listening!
