no. speaker placement/alignment is much more dependent upon room characteristics than on the electronics driving them. once you find the "ideal" placement, it should remain the same for virtually all upgrades you make on the rest of the system. but then, i know of some folks who still adjust the vta for every lp they play!
Speaker Placement/new component
I have a rather heated debate going on with a fellwo audio-NUT regarding if after adding a new component(amp,preamp,I.C.'s) if some experimentation with speakers placement should take place.What do you think??
