High frequency noise from Totem tweeter

Hi. I just wanted to ask for advice regarding an intermittent issue I've noted from my left channel Totem Forest tweeter. On certain notes/tracks (e.g. some piano notes from Diana Krall's Quiet Nights), I notice a high pitched (almost reverberating) noise that accompanies the note. It is not there through most of the songs/tracks and not noticeable at all on most of the music I play. This is never present when not playing music as well.

Current system is Arcam Alpha 7SE CD (as transport), MF XDACV3/X10V3/XPSU, Plinius 9200 integ amp, Totem Forests. Kimber Illuminati coax/Kimber Hero ICs/QED Silver Anniv Biwire.

I've tried taking out the DAC/Tube processor and the sound remains. I've tried switching the speaker cables' on the amp end and may have noticed less noise.

Is this a problem with the tweeter? Or a problem with my source (amp/speakers exposing the flaws from my CDP)?
Any advice is greatly appreciated. Thanks.

This is spooky, it happened to me also playing a diana krall song.

I phoned totem and in my case the high pitch frequency was caused by TWEETER speaker wire rubbing/vibrating against each other at certain frequencies.

The fix was to simply to open tweeter and wrap foam/electrical tape to seperate between +/- leading to speaker wire.

Hope this helps.
