Bi-wire speaker cable for B&W Matrix 3's

I have a pair of B&W Matrix 3series 2. They were the model under the 802's Around four years ago, I started using MIT Term 2 Bi-wire. I previously used Monster M-1000. Sound became more coherent, but less dyanmic. I now realized that MIT was a big mistake and a wrong match for this speaker. My question is can I put new life back into this 11 year old speaker with say Analysis Plus Oval 9 speaker cable. Any suggestions?? These speakers have been on the selling block for over a year, but I always liked them; but slowly began to dislike them after installing the MIT wire. All suggestions appreciated, My equipment is Aragon 4004 MK2; Conrad Johnson PV-8 Sonographe SC-1 CD player and VPI-19 JR table and a Blue Point Special cartrige. Thanks, Jimbo
