Thomastrouble,
The "paper clip and chalk block" things you're referring to are called "resistors," and they are available in different values (for more treble roll off) from Magnepan.
I have not had good luck using the Magnepan-supplied resistors (sound quality suffers) and I'm sure that there are better resistors of the same value and power handling capacity available if you want to buy and try some.
But one interesting thing I found recently was that using the Speltz Anti-Cable interconnects in combination with the Speltz speaker cables in my Maggie system seems to get rid of the excessive treble brightness without the undesireable sonic degradations caused by going through the resistors.
