I too find I prefer slight toe-in. As @ozzy found I found that the soundstage becomes flat when the tweeters are pointing directly at me. Some speaker mfr’s recommended having the tweeters line of fire cross about 2-3 ft behind the listening position. I find the soundstage opens up and the off-axis response is better when it crosses WAY further behind the listening position however. Interestingly I don’t notice too much else changing with my B&W 802’s beyond this, as I mess with toe-in. I don’t notice any change in frequency response from the sweet spot, as toe-in is changed. I guess that has to do with the drivers being consistent across their wide dispersion range.
Currently my walls are being painted after I had dedicated AC lines installed (woo-hoo!). So my system is dismantled and covered in protective sheets right now. After the painter is done by Saturday, I plan to reconfigure my couch to be closer to my system - will try a closer configuration to an equilateral triangle with the speakers moved out further from the wall (was previously 20” of clearance behind the speakers). I will try the 1 to 1.2 ratio referenced above. For me this means speakers will be 7ft between tweeters and 8.4 ft from tweeter to ear. I might also try being even closer to the speakers. I find as I move back in my room, I lose some of the crisp upper frequency detail that I hear when I am closer.
