Who positions their speakers straight ahead (zero tow in) and why.

My Cornwall 4’s are set up in such a way that they can be very accurately positioned especially as to complimentary angling. One listening night recently I was startled to hear a somewhat different and dare I say superior sound emanating from them. I wondered if some of my recent tweaks had suddenly "broken in" fully. It wasn’t until a few days later that I realized our Friday house maid had moved one of the speakers while cleaning. It’s very easy to move them angularly though they remain rooted to the floor at their mirrored pivot points. My listening/living room has some unfortunate furniture placements that are essentially non-adjustable. The speaker that was accidentally toed out more was dealing with an upright piano on its sidewall. That speaker had been accidentally turned outwards a bit towards the offending piano. The result was a slightly airier sound presentation that was very pleasing and a somewhat wider soundstage.

Anyone else here experimented with asymmetric speaker toe-in?

I have Magnepan 3.7i speakers.  I have experimented with many different degrees of toe in.  I have found for my room that having the tweeter ribbon on the inside and just a few degrees of toe in works for me.   The speakers disappear and have an expansive soundstage.  Huge width and depth.    When I oriented the speakers with the tweeter ribbon on the outside the center fill went to pot!  As with all things YMMV!

Well, I am. My room is large but asymmetrical, so I thought it was worth trying. I am far from done, but at this point my left speaker crosses ~2 ft in front of my head while my right speaker crosses approx 1 ft behind my head. They’re about 15 ft away from the front wall. I would say this is the best they’ve sounded so far.

Sometimes getting goofy pays off. It's what I like about this hobby.

I've owned three pair of Vandersteens and believe Richard recommended straight ahead.  But he also recommended some distance from sidewalls which is addressed by others here.  

Some other speakers I've owned worked best  aimed just behind my head.

So another vote for "depends on  the design of the speaker and room set up".
