One must always be weary of reflective finishes in the listening area. This gives the user the choice of finish that would produce a nice balanced sound stage. Remember this product is supposed to elevate the stage, not shift it laterally. Someone who is really in tune with there environment may be able to make an x,y and z axis change in one try but I would start with the z axis first then listen until they are comfortable then experiment with the x and y to fine tune . Empirical data should be applied as this this is such a ground breaking approach that no data has been published and Doc B is being quite tight lipped about it. I feel he should have waited before he announced this product until he has more data. Just my .02c
