Hevac1 is right. I have experienced the same thing. High back leather chairs will cause reflection problems much like having your chair against the wall. With a high back chair made of leather it's best to throw a blanket over the back.
Listening chair suggestions
I now have a dedicated listening room and I am searching for just the right chair to place in the sweet spot. I'm considering a recliner or maybe one with an ottermen. I thought an ornate barbers chair might work but it seems difficult to transport. Suggestions are welcome.
