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.

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.

The only one that I can think of is David Magnan and his Magnan Signature interconnect, which has a resistance of 30,000 ohms for a 4 foot length using Teflon ribbon conductors (non-metallic). I can attest that this cable makes a terrible phono cable, though sounded surprisingly good in the line stage.

Bruce, no, but I wouldn't be surprised if in some systems your other suggestion might be found by some listeners to work just as well as that interconnect. Provided, of course, that the string has good pedigree and is well vetted by the cable manufacturer, is specially treated with some esoteric compound, and is marked up to audiophile price standards.

LMFAO...Al, you're a funny guy! Thanks for the chuckle.

So if I am trying to buy a pair of interconnects that do not color the sound, what does one look for in terms of construction and measurements?

Unfortunately, this is not so easy to do for the many reasons that Al has already mentioned. Also, not only for the reasons that Al mentions, variations in electrical parameters between components and cable lengths, but also because individuals have different personal hearing variations on what "color the sound" actually sounds like. I've witness quite a few disagreements over which cable was actually the most "transparent", even in the same system, at the same time. Different people just hear what they perceive as colorations differently, even if all of the electrical interactions are consistent.

Obviously there are some cable brands everyone pretty much agree that color sound, but even these brands can work well with the right ancillary equipment. For instance, a cable with a emphasized treble region can sound fairly neutral with warmer sounding electronics or speakers, just as warmer cables can sound neutral with brighter sounding equipment. This hobby is all about system synergy and personal musical taste, therefore many experiences are not agreed upon. Just like choosing a favorite flavor of ice cream, or wine, many may make recommendations of their favorite flavors, but that may have no bearing on what flavor would suit you best.

And beyond that, it probably comes down to researching the experiences of others (while trying to calibrate the credibility of the person providing each report; for example I would consider the many cable-related comments Jmcgrogan2 has provided over the years to be especially credible), and if possible trying a variety of cables, such as via The Cable Company.

Thank you kindly Al, I am truly humbled. I had no idea anybody even read my musings, let alone gave any credence to my incessant rambling. ;)
