General passive-line level filtering issues. (BD-Design)

Hi Stephan,

That means I´ve to split the line signal before the main amp, which I do
with a passive network, like the one published in the forum.

This might work if you have a preamp with a very low output impedance, it will not work with a TVC or even tube pre-amp as their output impedance is a lot higher that your 40ohm pre-amp. So, that is not the path I will walk simply because most people do not have such a pre-amp... :no:
