i point my speakers almost straight with maybe 2 degrees toe in.  they are about 9' apart as measured from the center of the coaxes.  ears are about 7'8" to the coax and are below the coax about 6".  please read what Pierre has to say about listening position.   it is general for sure but some good info here.  just avoid heavily padded chairs or couches right behind your ears (which is why i use the Lafuma cloth covered recliner).  http://www.mapleshadestore.com/freeupgrades.php

Most speakers tend to sound a bit more rich and full, emphasizing the midrange over high frequencies, when you lower your listening position. That is true of the 3.7s though for some reason less so of the 2.7s which seem to maintain a very even tonality over a wider vertical area. The 2.7s might have the most consistent tone over a wide axis of any speaker I’ve owned excepting the MBL omis.

I sit on a very large sofa that I had custom designed for deep seats and somewhat high backs to facilitate comfot and support for watching movies and long listening sessions. I specifically made sure the back supports my shoulders but ends before my neck/head so as not to interfere with direct sound from the speakers.

However I can recline further, feet up
on the ottoman, resting my head into the pillows. At that point the sound changes a bit from the reflections from the pillow around my ears, similar to when I introduce some more room reflection by moving my curtains off the side walls near the speakers. The sound brightens a bit, gets a bit more lively and present, a bit more expansive though less image focus. It can be enjoyable too.

But tonality becomes a bit more whitened and homogenized so mostly I listen with me back supported, ears clear of the back cushions.

Lafuma - I have two of those, mesh versions, that I use in the yard during summer. Fantastic for taking a nap in the shade!

Last night I was using a wooden low-rider style. I kept adding padding until my ears were in the range 32-36. I thought that ~35-36" sounded best-ish. I intend to dial that in more then return to speaker placement.

At that point the sound changes a bit from the reflections from the pillow around my ears, similar to when I introduce some more room reflection by moving my curtains off the side walls near the speakers.

I am certain that my ears relative to the high couch back is a big part of the differences in sound I heard. In my case, I think that and listening height are more important than differences between, say, 8 and 9' distance.
