Can I pick someone's brain on turning your old stereo to wireless?

I have an older stereo system that I love and that I have had for many years - JVC. But every time I move speakers, I have to thread speaker wire to them. I guess that is why many systems have their speakers right next to them. I have placed speakers around the room, and would like to use them for both my TV and stereo. What converter would allow this to send sound wirelessly to my old or new speakers?
