I own the Aperion 400 series which I suspect doesn't let my Outlaw equipment stretch its legs. Of course the Outlaw equipment will sound better with upper end Aperions. (Or future Outlaw Floorstands perhaps? With an Outlaw Center? And Outlaw Surrounds? Hint hint?) Even though the 400 Series are the lowest rung of Aperions line, they sound fantastic. Once I got everything dialed in this system delivers. With me, Aperion Audio & Outlaw Audio have a lifer on their hands. Both Outlaw and Aperion have the best Customer Service I have ever dealt with. I'll always refer anyone in their direction.
