I have a tech who is a wizard with action. I have all of my guitars set up by him and I have absolutely no fret buzz. It is a function of neck relief and fine tuning of the nut, and the bridge and saddles. I had one guitar that would buzz and I took it to him. He said there was no way to get it right without a fret levelling. He did that and now it is probably one of the fastest buzzless guitars I own. You should be able to get the action nice and low on your Suhr. It just takes some tweaking. You may need a fret level. You can check it with a steel ruler. The high frets will be very obvious as will low ones.
