MuMETAL is effective at reducing induced noise in signal sensitive gear with high gain and small signal levels. If you are trying to achieve the quietness of state-of-the-art hifi, try enclosing transformers with MuMETAL.
1 circular layer (overlapping ends) around a transformer can attenuate by up to 75%. More wraps = more attenuation.
Edges will be sharp. Caution when handling.
