What do you all use for a mixing chair? high back vs low back I have nice high back leather chair but don't use it because I'm concerned I will get some imaging and possibly even higher frequency reflection issues effecting my mix from the sound hitting the back near my ears, so I stick with a low back. I ask this because I've noticed a lot of studio use the highback chairs in their promo pictures in front of their consoles. Think I'm over concerned here? I'd love to be sitting in a bit more comfort.
