When not evaluating some element of the music or equipment, I browse reading materials or just lay back on my listening seat and enjoy.
If on the other hand, I am trying something new or trying to ascertain if something in the system is not doing the right thing ,e.g. a tube swirling the drain, I actually sit slightly forward staring intently at my setup for as long as is necesarry, to figure out what the issue is.
BTW staring at the equipment rarely yields an answer but I can't seem to concentrate on the sonics without fixing my gaze. I know many close their eyes or dim the light but I am usually tired and find myself waking up the next morning, with the equipment on. This can be very bad if I was using a turntable. Cartridges with paper covered styli rarely sound good.
I imagine this would be the case for many- either just relaxing with or without reading etc. or concentrating on the sonics.
I rarely get up and dance, I was never a dancer and now I am an old fart, or do Kareoke (sp?). Although its hard to resist trying to sing "vincerro"at the end of a good rendition of Nesum Dorma.
