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 had a very similar experience where i was getting a crackling/interference/whistley sort of noise on the left side and it was driving me bonkers. After all of the cable switching I read about this phenomena called Tube microphony. Since I have a tube preamp, I found that that the tubes for the left side were the culprit. I hope all goes well with your diagnosis because I know you won't stop til you have this thing sorted out. Keep us all posted.
