In contrast to the half-second or so R60 at home, the finest concert halls have R60 times on the order of two seconds. Hence the difference that Alan notes.


I read that, and then had a seizure.

Are you implying a correlation? If so, you may just have forgotten your mid-day diazepam, 'cause you were too sh'faced to remember.
