The toe in effect applies to all speakers really , if you listen to classical mostly, live or recorded and have a strong imagination straight ahead will sound more natural than with Toe .....
Multi track Studio recordings better with toe ..
I found this to be the case with my Magico speakers, but it took a very long time to find the right position in the room. Toe in makes it easier and quicker, but it was a compromise. Aiming those speakers straight ahead, resulted in a more natural presentation.
