Not as such, but everything else being equal, a higher tension string will "travel" less and theoretically should buzz less. Although I wonder if you've just added extra relief by increasing the amount of pull on the neck.

relief is fine. As I said, it was set up by my local tech. He said everything was perfect. It must be the tension thing which reminds me, how do they increase the tension in strings without changing the gauge?
