I had Audyssey xt and never really liked what it did, so i left it off. Dirac is another story entirely, it really brings the whole package together , its really hard to put into words, it just makes everything seem more cohesive. I have heard good things about ARC and how they do bass is good as well if i had the money. I have no money sick and i want PJ.

DOG is GOD spelled backwards.
What others think of me is none of my business.
