Another way of looking at it is suddenly displacing your hearing point by 2 microinches(0.05 micrometers).....your heartbeat probably does that...or blinking...or clenching your teeth....or the remodelling dust settling on the furniture.....or.....

Group delay of a speaker will only be important for single source fidelity..and I'm not considering that at all.

I am considering only the possibility that the left-right signals will temporally shift independently of each other, causing temporal relative shifts in the 10 to 20 microsecond range, as that is the shift magnitudes needed for a one foot shift of apparent source at ten feet distance directly in front...ears 6 inches apart (as if it's adjustable). If I find 1 usec shifts from skin effect....that ain't audible.

Dust? get this...

My ex father-in-law is a real prominent bridge/tunnel engineer in manhattan. When the first plane hit...MTA called him to get there fast and eval the structural integrity including the subway system. He got within four blocks when they collapsed (there are times when traffic delays are a blessing). He got home covered head to toe..left dust everywhere.

When I was spackling my condo kitchen, I made huge amounts of dust...My six year old daughter saw the dust on my coffee table, and asked me if I had been in the city..
