Toe-in or NOT toe-in ??

Trust your ears! Try it both ways (having a helper shift the speakers while you listen with eyes closed). Really depends, IMHO, on the speaker and the room. My Spendor 1/2s in nearfield are pointed right at me. Downstairs, my SP100s sound best straight ahead and sound "off" with any toe-in whatsoever!

Hi Opus, all is well! There is also the Cardas way, using the golden triangle ratio. It's fairly easy to use masking tape on the floor and slide a speaker along the line to see how it sounds. It's an interesting experiment if nothing else.
My listening panel hates toe, even when their own manufacturer uses it. I know, each to their own.
I set my Harbeths up with a good spread and toed directly at me, where I can no longer see the inner sides. Perfect for my room and ears.

If the speaker designer cannot be reached, try experimenting yourself. Only you can find out the results yourself. Bear in mind you may prefer the results when the speakers are toed-in while another might not like it and prefer them pointing straight ahead.

Your ears are the best guide.
