Recently, I have been experimenting with the nearfield speakers placement as suggested by Audio Physic and it has improved the overall presentation of the music that is being played. I will still need more time to optimise my placement but I initially started using the Cardas method awhile back which I thought worked well then. At present the palpable factor has moved up a notch but I seem to hear a bit more bass boom than before. IMO it is a trial and error process to fine tune speaker placements and there is no one "best" method/rules but perhaps some combination of methods.
