Diagnostic suggestions

Speakers: Magnepan 3.6R
Amp: Pass Labs 250.5
Preamp: Pass Labs X1

Problem: Tweeter in Left speaker was exhibiting a kind of static for one or two songs featuring piano. Problem is intermittent. Tried a variety of diagnostic things and decided to replace the tweeter as that seemed to be the issue. Problem continues.

Switch L-R output from preamp to amp. Problem stays in L tweeter. Put connections from pre-amp to amp back to normal L-R configuration. Then, switch L-R speaker cables in back of amp--now, problem is in R tweeter (not L tweeter).

This would suggest to me that the problem may be in the amp itself. Have I missed any other possible interpretations? or diagnostic options? Thanks for your help.
