I just got my QS8s about a month ago and have been experimenting with their location. Haven’t yet found any spot they didn’t sound great. Anywhere from directly to the sides to four feet back against the back wall using just the stands or going up to seven feet.
If you have the time experiment like sirquack suggested. I found that in my room and to my tastes they sound best in the back corners of the room with the tweeters facing parallel to the back and side walls while sitting about two feet above ear level.
Have fun with them.
