Well, it's not _just_ about the speed of sound, there are also things like the 
speed of attack of different instruments and so on.

Then again, ever been to a performance of one of those pieces that ask for some 
musicians to be placed in different locations round the back of the concert hall 
for spatial effects?  Things can get fun with that ... :-)

So, if your latency is 22ms, think of how that corresponds to sound travelling 
in space: you only need to be separated by about 7.5m for that kind of delay to 
kick in.
