[Elecraft] K2 Audio Filter Question

[Paul Huff]

I am getting ready to install the KAF2 audio filter in my K2 and I would 
appreciate any opinions on the following:

The manual says that installing the W1 jumper will cause AF1 to be skipped and 
only AF2 will be available.  Other than reducing the number of button presses to 
get to AF2, what would be the reason for doing this skip of AF1?  What is the 
main difference between AF1 and AF2?

Thanks in advance for any opinions.
