Hi, my system includes a Onkyo TX-SR603x reciever, two (tower) Onkyo SK-60s in the front(specs=120 watts, 36Hz-120kHz, 91db/w/m, 8ohm), that are old but still rock. And I have Yamaha bookshelf speakers for my two rear speakers, and a 12" Velodyne DLS-4000R Sub. Now, my problem is that I need a center.... I want an onkyo to match my two fronts. So I was looking a either a Onkyo D-105C, or a Onkyo SKS-101(with two rears to act as my 7.1 rears). Which would work best? If neither are a good answer, any other ideas D-105C - http://www.us.onkyo.com/model.cfm?m=D-105C&class=Speaker&p=i) SKS-101 - http://www.shoponkyo.com/detail.cfm?productid=SKS-101&modelid=170&group_id=1&detail=1&ext_war=0
