I just read the instructions for the "Sumiko Master Set" and they're ridiculous, except for the fact that you need sound to set up speakers which you then should listen to to see if they're providing what you want to hear. That's it. Yeah, you move them around a little, ultimately sit between them, and there ya go! You will not be able to sit just anywhere in the room and get great sound as, well, that's just not how these things work with a dissimilar stereo signal emanating from different places, room reflections, vastly dissimilar dispersion characteristics from dipole to horns to sub integration, different personal preferences from listeners...Master Setting...I really hope shops don't charge for this nonsense.
