The "impedance compensation networks" or "Zobel's" as supplied by Goertz are not wired in series with the signal. They are placed across the speaker terminals in parallel with the signal path. They only come into play at frequencies WAY beyond audibility and are only used to help stabilize the amp that they are connected to. These are in NO WAYS similar in design to MIT's, Transparent's or other cabling with networks of "filters" built in. Sean
