This has been a know problem for many years.  In the Tips & Tricks 
section for AN1x-list here at Yahoo! Groups

you will find and HTML doc: tt_audible_pop_click.htm 

"AN1x Makes an audible "Popping" & "Clicking" at Startup"

This documents the steps I took to have the problem corrected by 
Yamaha while my AN1x was still under warranty.  I'm uncertain how 
many others had the issue addressed by Yamaha or what it would cost 
for an out warranty repair.  You will need to contact Yamaha Customer 
Assistance and inquire for yourself.  My reasoning at the time was to 
have the problem corrected before it deteriorated further.  I've 
experienced no further issues in the years since...
