In Reply to: Paper Cables? posted by Steve Eddy on March 23, 2004 at 02:18:06:
It looks very good, the gauge of wire used limits to use as an interconnect. Using 18 ga or so would be better for use as a speaker cable.
Someone gave away DNM hookup wire at a DIY meet a while back. I used it to wire up my Pearl phono. It is quite close to 300 ohm antenna wire but has high temp plastics. It does not seem to pick up hum.
Does the use of paper have offer anything sonically?George

If you've got a large loop area, it'll certainly pick up hum. But if you haven't any strong fields coupling to it, it's often not a problem.

Dunno. As I explained to Owen, I haven't listened to them yet. :)
I was mainly just exploring what could be done with paper while keeping the dielectric involvement as low as possible.

One quality I am interested in with single conductors is damping the wire. This is a good start but I think the wire surface needs a tension provided by a laminate or coating. So take the paper finished wire and dip in a damping/adhesive/finish and or?TC

==The one that makes all the single conductors sound grainy in the vocals. But I am refferring to speaker wires not IC's.Ok. Thought you had something more specific in mind. It could be a modulation effect rather than a resonance in which case damping wouldn't be very effective.
Of course you could just avoid single conductor cables. :)

Still the romance of a single conductor is alluring. And again the paper design is shweet! I still have quite a few magnet wire IC's and such around. Will probably build a paper IC for fun.
Modulation effect? Another term for electrical resonance?
Also still thinking about tungsten and steel wires. And I note that some desigers are fanatical about resonance control in cables, is this not what led to Cardas wire stranding? Kimber stranding? Electrical resonance? Jena braiding?

Not gonna build it with magnet wire are you? That would kind of defeat the purpose wouldn't it?
Modulation effect? Another term for electrical resonance?
Not quite. More like a change in one element affecting the parameters of another. Say for example mechanical energy due to vibration changing the geometry of a cable which changes the cable's parameters.
Also still thinking about tungsten and steel wires.
Yeah? Well just don't think about it on Cable Asylum. :)

The resonance control in those products are geared toward mechanical resonance rather than electrical resonance.
But resonance in itself isn't a bad thing. Everything is resonant at some frequency so you simply can't avoid it. If you're shooting for objective accuracy, the thing you want to avoid isn't resonance per se, but ringing and overshoot which can affect transient performance.
You're in the speaker bidness, so you know that an acoustic suspension system with a Q of 0.5 is critically damped and will ideally have ideal transient performance with no ringing or overshoot, whereas Qs above 0.5 are underdamped and will have increasing amounts of ringing and overshoot and not so ideal transient performance.
So while a cable is resonant both electrically and mechanically, I don't see there being any problems in a technical sense unless the Q of the resonance is greater than 0.5. If it is greater, then applying damping will bring it down. But if it's not, I don't see any point of adding any damping.
