crackling sound out of right speaker

I am hearing a crackling noise coming from my right speaker.
I have done the following:
Swapped cables (from nordost to MIT)
Swapped left & right sides (left to right and right to left)
Swapped tubes in the amp
Still I have the same crackling sound when no music is playing on any inputs.
My system is:
B&W 802D
Nordost blue heaven speaker cables (all nordost interconnects)
VTL 2.5 preamp
Sonic Frontiers SFS 50
Any thoughts?

Looks like it's time to change filter caps. Visualize them at the electrodes if there are any residue.

I never heard filter caps do that.

Do you have another pair of speakers?

Did you check the tubes in your VTL 2.5 preamp? Or you have another preamp to try?

Audiolui, the OP swapped the L and R amp cables, therefore, if the pre was at fault, the problem would have transferred from the right to left speaker.
