In Reply to: Do high Impdance IC's tame hot treble? posted by Roublard Cache on March 21, 2007 at 09:42:29:
Just out of curiosity, if you want extra resistance or capacitance in a connecting cable, why don't you just solder in a discrete device? That would have the distinct advantage of letting your 1) experiment with different values, and 2) keeping the precise value that gives you the effect you desire.(It is somewhat interesting after all that effort to get tone controls out of high end electronics that we often now use expensive cables on a trial & error basis to alter the frequency balance.)

I don't have lots of soldering experience but for making cables, but I do have access to lots of cable and a multimeter. In general, does a higher impedance cable tame highs? That way I can rule out cable or wire that is low impedance, and not experiment with it.
I know what you mean about tone controls or treble level controls on speakers. I have heard people talk about how they are bad, but when you are in a plaster room with a concrete floor, and can't really change much (I don't own the apartment) they are a lifesaver. I think my next pair of speakers might be Vandersteens just because you can adjust the treble level.
Higher cable capacitance is going to roll off your highs more than impedance (which is what they call resistance for AC signals.) Higher impedance will add another variable to the interaction between the output impedance of your preamp/source and the input impedance of the power amp. That effect will vary with the specific technical details of your equipment. However, IC cables in general don't have much in the way of extra resistance that is important to the circuit. You'll probably see a greater effect from the capacitance (and possibly inductance) issue.
Thanks! I had capacitance mixed up with impedance. I did some research and have found some wire that offers a specific high capacitance and will try that.
