What are important features in a listening chair

Im surprised more people haven't chimed in ont eh ear cupping.IDK whether Geoff is right, but assuming he is, my guess is most rooms/systems do not provide ideal dynamics 

Satellite dishes need to be larger for weaker signals (for the same frequency). It’s the same thing with cupping ears. As you turn the volume up and/or improve room acoustics cupping the ears is much less impressive.

Yes. Increasing volume reduced need to cup ears. Now my arms don't ache so much.

Little known secret: Sitting in a IKEA Poang Chair, wearing an Urban Sombrero (from Seinfeld show) tilted at precisely 45 degrees, almost replicates exactly the acoustics of Carnegie Hall!
