Headphoneus Supremus
If it's caused by mechanical moving of the glass then you could try special tube rings that absord them. As such they can't be amplified through the amp.How often do you hear the ringing with Fei Wan? I’m hearing from a friend who has the SP3000T and is using it with Campfire Fathom that the tube mode is just about unusable with very sensitive gear. This obviously doesn’t apply to me with me using Storm and sets that aren’t so sensitive, but now I’m curious just how noisy it can get. I received my purchased unit yesterday but I haven’t unboxed it yet as I’m waiting for more data on this.
They're also called O-rings and cost next to nothing.
