The 87mH Pleiades (proximity EQ filter) is made with Siemens core and has higher series resistance due to higher turns needed.
The 82mH Pleiades filter is made with Magnetec core and has a lower series resistance due to thicker wire and less turns needed. This is due to the higher inductance index of the Nanocrystalinne core to the ferrite core.
The Siemens-Epcos sounded more full and the Magnetec more clear. The 82mH Magnetec may have suited better the MD441 and the 87mH Siemens- Epcos the D112.
Setup:
Mic - Pleiades filter - Sony TCD5 PRO I
