Re: Not meant to be a Speaker cable!

Posted by Jon Risch on July 29, 2000 at 09:07:08:
Yes listening is the final arbiter. However, I have done an LOT of listening to cables, to different materials, to different cable construction experiments. I have listened to computer ribbon cables, compared to some of the finest retail cables of the time, as well as to my own recipes. So what I speak of is more than just theoretical ramblings.
A:Low Inductance means extended bandwith-- HF roll off??
Yes, under some conditions of length, speaker load, etc, the inductance of the speaker cable can roll-off the highs, and soften transients and recorded hash. With zip cords, the PVC insulation's sonic signature is tempered by this softening, however, two wrongs don't make a right, but they do make it sound more tolerable. Remove the inductive softening effect, leaving the PVC, and you get some of the artificial zip and zing, even harshness at times, that PVC can bring to the table.
B:Don't most of today's amps have Zobel networks so capacitance not a problem?
Most of today's amps have an output inductor AND a Zobel, and technically, only about half are what would be called unconditionally stable, that is, there is no kind of load within their rated load capacity that can cause oscillation or instability. Typically, the very high slew rate amps, amps with extended bandwidths, these can be prone to oscillations with 'excessive' capacitive loading. Also just plain poor designs.
C:Are the cables you mention 70c a ft?--level playing field please.
No, the ribbon cables I mention are over $5-10 a foot. The cross-connected Belden 89259 coax (recipe #1) runs about $2.50 a foot.
What level playing field? Your $5000 cables might not sound any better than the CC89259 at $2.50 a foot. The CC89259 might even sound clearly better to you. Now that would smash the playing field.

D: No I am not dumping my N(oops!) cables just yet!
Didn't think so.
