Gonk,thank you for your quick response.So that I am clear, you reccomend that I attach the speaker cable from the respective mini to the corresponding 2200. I would then attach the balance cable from each 2200 to the respective left and right channel of the 990. The current left and right surround speaker wire remains with the 7500 but where does the current left and right balanced cable supporting those channels hook up to the 990 since the 2200 cable now occupys that space? I hope this makes sense.
