What made you choose the loft 20 as a center? You're generally advised to have a center that matches your L/R speakers. A better center would be the Infinity pc251 or 351. For surrounds, another set of 163's would be ideal, but anything will work. And, yes, your Onkyo will work fine with all this. Another option would be to move the 163's to surround duty, and pick up a pair of 363's for fronts. Frye's has the 363's on sale for $107 each.
