It depends on the speakers and the room. I have had a pair of Mirage M5si's for 12 years, set up in 3 different houses. In the first house they sounded best slightly toed in. In the second house they definitely sounded better facing straight ahead. And in the third house (where they've been for 9-1/2 years) they sound best toed in a little more than they were in the first house.
In each case, the toe-in I settled on or eliminated was based on the best image focus and clarity of sound in the listening area.
Some speakers even sound best angled at a point about a foot *in front* of the listening seat.
The only way to know is to experiment, and yes, it's a pain in the ass, especially with big spiked speakers, and those Mirages weigh 85 lbs. each. Still, the perseverence paid big dividends in listening enjoyment.
