My usb module was packaged the same way as other guys here but it got here ok but they were more problems to come installing driver, compatiblity issues also popping issues never had to take an attenuator apart in an amp ever and i did it twice and it didnt solve the problem always comes back and this amp is only 6 months old of course they are not going to change it they say its normal .Anyways i got fedup i sent my amp to PARTS CONNEXION today to have a khozmo 50k 48 step attenuator installed .Thats that .
