I'm listening to the Bifrost MB /Lyr 2 combo right now, on my Audeze LCD-3f. No noise, not even when I stop the music and turn the volume past 3 o'clock. It's very clean, especially for a tube amp. 

 

[ofaisalo]

so why it happening with me
maybe they fixed the problem with lyr 2 ?

Could be your tubes.

yeah, sounds like you have a bad tube that's about to go and has become very microphonic.
