I recently changed out my fixed chair for a Herman Miller Aeron chair on roller casters. While there is a specific distance I should sit from my speakers based on setup...I find that different recordings can be optimized by having the ability to easily move closer or farther away from the speakers. Anyone else feel the same way ? I think in large rooms where you sit a good ways back, it might not be a benefit, but for me being a littler over 10' back, having the ability to easily move a bit closer or farther away yields a better listening experience.
