Of course. Even though quality can be a moving target, the math is pretty easy. If you need to be at a quality level say, of 8 on a scale of 1 to 10, the quality of your parts can't be at a level lower than 8. There's simply no way to make it up.
But it's more than just using "high quality materials."
My son is a pretty good grill cook. So is my friend, who is a professional caterer. If I gave them identical cuts of meat to grill, which one is likely to turn out better?
It's not the material that matters, it's who's doing the cooking.
