That is your likely problem. Spokes that were put on by machine are almost never unwound. That causes a tremendous amount of tension at the head and ping, off they go like Marie Antoinette.

And if you replace as you go, they will all eventually fail. You should save yourself the hassle and replace them all. Wheelsmith, Dt Swiss, Alpine or whoever, it doesn't make much difference. Same can be said about straight gauge or double-butted. As long as the wheel is built properly, they are bullet proof for regular riding.
