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?

Polk and Vinylmad, The OP's problem has to be in his Right speaker or the cable leading to it. That's been settled, I think. Good thought by Miner to check any jumper cable that is being used to connect among terminals at the rear of that speaker. A loose connection could conceivably be a factor, either inside the speaker cabinet or at the speaker inputs.

I brought the pre, amp and right speaker into the shop, the owner assured me it wasn't the speaker, he believes it's the input tubes in my amp, he loaned me a integrated amp and after hooking it up, the right speaker sounds fine. ill let everyone know what the actual culprit is as soon as I can.
thanks for all your suggestions

That seems irreconcilable with the fact that switching the L & R connections at the amp outputs did not cause the problem to move to the left speaker. Did he offer any comments on that?

I did some more troubleshooting prior to bringing my equipment in and the issue moved to the left channel when I swapped left and right speaker cables, I guess we'll see what happens when I get my equipment back.

Blue Heaven must have a crack or poor termination somewhere. Opening shrink tubes may be necessary. Try to use different speaker cables or better use generic speaker wire just for the test.
