I found this
"The FR-4 works very well in most audio applications. However, it is a
very hard material and has a tendency to vibrate. This might cause
tiny current changes in the components on the board, which, especially
in very low level circuits like MC phono preamps and microphone
preamps can cause unwanted “sounds”. Teflon base-material, which has
been developed for HF circuits, is much less prone to vibration.
Consequently it is very much preferred for low-level circuits."
any comments?
