Sorry, and don't mean to offend any one, really. But I listened to the pipedreams and could never buy them. The other is avantgarde, I wouldn't say they suck but with the price tag they have, they suck. I don't think there worth it. Now at maybe $2000 a pair I would buy them just cause they look neat, but I won't play them. Sorry, but thats my imho.
