Mennis,

I’m not the best to help with this, but what interconnects/inputs are you using.? Are you producing sound using analogue inputs/feeds sans ‘crackle’.

You might try a different interconnect, or a different optical/coaxial digital input choice to try your interconnect through.
It’s possible you’ve tried all this or are meaning something different.

Crossed my mind since in my past I’ve had two incidences of that kind of noise through the speakers. The first was an interconnect suddenly gone bad when recently moved. The second was a loose connection to the post.

I’d be utterly crushed, since I’m the want to play with it NOW crowd. But I do know, if its internal, per Outlaw's past track record they will be on it surprisingly fast. It’s bad luck it hit you on the weekend.
