Sweet another AR-90 owner. Love mine. I wouldn't worry too much about biamping them the 1.0t is fine. Now if you do recap them I suggest Solen all around. Sound nice and should last "forever" I even did the big caps since I have no intention of selling them. New binding posts and they're all set. I run mine with a BillD C-1; another great piece of Carver gear. Good luck and Welcome!
