Widening my soundstage

What are the demensions of you room, where are your speakers placed, and where do you sit?

Listen, don't do anything yet! If you really want to get down to it start by ruling out the obvious and least expensive stuff first. Answer the above earlier post. Also give info. on the type of room you have, i.e., sheet rock, plaster, ect., location of windows, location of furnishings and any room treatments you have applied. Then wait for feedback. Unless you have these first principle correct, that is properly placed speakers, listening chair and room treatment, the rest of the suggestions are putting the horse in front of the cart. Get this correct first then look at your other variables. $2,000,000 worth of cabling or equipment switching is less effective then proper set up!
