Yes, I agree and in my earlier post I stated; "it's easy to be loud, just 
buy another amp and crank it to the  max.  Now being good, well that takes 
skill, knowledge and talent."    Also, I've mentioned many times that good 
audio has a lot to do with good mike technique.

Bob Heil has a very good presentation and demonstration that can be found at 
http://www.youtube.com/watch?v=tX9J6Vre3j8   The mike technique starts about 
20 minutes in and runs for about 8 to 10 minutes.  It well worth watching 
and there's lots to be learned.

Bob, K4TAX
