I suggest that you defer judgment on this until you're trying to 
copy very weak signals during a band opening. The additional preamp 
at the patch point (in my case an ARR) definitely DOES improve RX 
sensitivity at times when the external noise level is low. I'm not 
suggesting that the ARR is better -- indeed, I doubt that it is. 
But it was bought and paid for when the K3 showed up, and it works 
fine. :)
