Hello on highway sixtyone, sorry about your diagnosis, but i would get a second opinion from another doctor, if it is indeed true, and you can afford it, go for the best of the best, why not. I am surprized no one has mentioned the best of the best. Lirpa Labs is by anyone's standard the best of the best. They will also install and tune your new system. Definately the best of the best for someone in your position. Good luck and hang in there. One note, if i have anything to do with it, none of us will be around in a couple of decades, and no child will be left behind. Best wishes, George W.
