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?

I am as puzzled as you may be, but the fact remains that the amplifier may be blameless. Anyway, I understand your running out of patience in a case like this.
I have talked to the tech on the phone, I'd rather not him come to my house. I;m over it....
Best of luck to you with that. Please report back on if the problem has in fact been resolved.

Based on your earlier descriptions, something still seems fishy.
