I have a hunch that if I moved the couch, the speakers would end up getting moved too...into my new bedroom...in the trailer...down by the river...
the system actually sounds quite amazing in its current position...the towers are about 14.5 inches in from the rear wall and just over 32 inches in from each side wall - very nice and balanced sound, top to bottom, with no real dips or peaks that stand out (don't have any of that room eq stuff with this basic 2 channel stereo - it just sounds great...unless you're sitting on the couch between the speakers
)...and the front plane of the speakers is ahead of anything that might directly absorb/reflect their output (except that darned table lamp to the right...I did try moving that out of the way back in 2011...I found the lamp replaced back in the same position the next day...and it wasn't until later in the week that I was able to find my newly-missing dac...in the furnace room...behind some boxes of Christmas decorations)...
so...quite, quite, quite happy with things as they are (though may try for the single size chair in espresso brown leather when the time comes)....
