What is Low Impendance for an interconnect?


I have been reading some of Roger Sanders views on interconnects and he would have his listeners utilize braided interconnects that are low impedance.

Any thoughts on this subject?

What would be considered low impedence for a preamp/amp interconnect?

I am a newbie just trying to learn

Well said Al!

According to that second statement, most expensive interconnects are poorly designed since they will reveal differences in sound. Maybe there are also poorly designed amps and speakers out there too that will reveal differences in sound. ;)

In that link you provided Al, he does address capacitance in the section titled Capacitance under speaker cables towards the top of the page, where he says:

Capacitance should be low. This is not as critical as inductance, but it is important.

Thanks, John.

As you probably realize, my reference to the non-mention of capacitance pertained to the section on interconnects, not speaker cables.

For the OP's info, generally speaking:

1)In the case of analog interconnect cables, capacitance may be significant, especially if cable length is long and/or the output impedance of the component driving the cable is high. Resistance and inductance are unlikely to be significant, unless they are unusually extreme. (With the exception that the resistance of the shield or other return conductor, not the signal conductor, can sometimes become significant if ground loop issues are present).

2)In the case of speaker cables, the situation is the opposite. Inductance and resistance may be significant, especially if cable length is long and speaker impedance is low. Capacitance is unlikely to have much significance, except in the case of a few cables that have ultra-high capacitance (such as Goertz, as mentioned in the paper).

The second quote from Mr. Sanders (all well-designed interconnects sound identical) is so bizarre that I personally wouldn't believe another word he said. I realize that "well designed" are the weasel words.
A further point concerning his emphasis on low resistance in interconnects. Referring to some "poorly designed" interconnects, he states:
Some of these interconnects with tiny wires have several thousand ohms of resistance and can adversely effect the frequency response of your system.
It is unimaginable to me that any half-way competent designer would create an interconnect cable having a resistance that remotely approached several thousand ohms. In fact very few designs (poor or not) approach even a few ohms, for typical lengths. And most would be less than 1 ohm for typical lengths.

As I indicated earlier, the resistance of analog interconnect cables is usually not a significant parameter.
