hey when you're finished with the cat can I borrow it for some quantum experiments

What a cute kitty!!! Is that Schrodinger's Cat?

Hey,

I braid my wires, because it's sexy and I still got a HUGE roll of teflon insulated wire.

To make it even worse, I usually use 4-braids unlike 3-braids you often see. Reason? It is because I am too incompetent to do 3-braids. I keep on forgetting which wire goes where. My teflon wires are ALL white! 4-braiding is much easier for me. Plus, the finished product LOOK more professional. AESTHETICS!!!!!!! I want my wires to LOOK sexy.

As for techno-babble, this whole issue is more related to the most difficult domain of physics ... E&M. E&M is probably most elusive. (Well except some new stuffs like QField and Strings, but who cares about those. ) Hard to believe Einstein was doing something far less sophisticated than E&M.

I think the key to understand fields in braided wire is it's "orientation" with respect to the ground wires. Which includes more than just distance, but also direction. Wires in braids bent different direction every other braid so "direction" is all over the place. ... ... ... ... It's weekend, I am not supposed be working. Rest is up to you.

haha thanks all for your support of my scientific babbeling. I just finished my quantum course so I had to use it somewhere!!! its not like it actually has any other real work applications....

I think the thing to wonder is that if you are using a sleeve where you can't see the braid underneath, is it really braided. We don't know if the cable is braided or not, so any sound percieved would be the sound of both a braided and nonbraided cable......

Hey,

Quantum you say? Ah then you must be one of those good little physics-major. You can try Quantum Finance. Heehee. I am pretty sure your prof will get a huge kick.

As for this shibang, go find friends who have a part-time job designing wave guides. They have this AWESOME E&M simulator and it will probably work for COAX and parallel wires.

They'll have a good, hearty laugh at you if they find out you're asking about audio cables. 20kHz and below is considered DC to most of the high-frequency EM/transmission line guys.

If it will go down a wire it is DC.

Eh?

Talk to any of the guys who do real work in the E&M area. As far as they are concerned if the energy can be transmitted down a wire (i.e. a wave guide isn't needed) it is boring, and thus as close to DC as doesn't matter. If it needs black magic and serious mathematics, then it is interesting, and thus AC.

Applied to audio this rather shows how utterly deluded many of the market-speak ramplings associated with audio cables are.

conductor geometry is not all rubbish, there is real science behind a geometry of a cable. Mainly pertaining to capacitance and interference rejection.
post #26 of 31
I don't think anyone would disagree about that. However it is pretty easy stuff in comparison. It most certainly does not involve any of the psuedo-scientific rubbish purveyed with regularity in audio circles.

All this psychobabble makes me want to go out and buy some quantum purifiers for my interconnects

Does anyone here have a capacitance metre who can check the capacitance of a tightly wound litz braid and 3 straight wires in close proximity unbraided over 1m?
post #28 of 31
Egads!! Quantum Purifiers - they must be the ultimate in snake oil. There is sheer artistry in the scam that pushes those things.

Braiding for capacitance of course involves braiding both signal and return, and has nothing to do with litz braiding. Even though there are cable purveyors who will try to tell you otherwise. The well known example was Naim, whose amplifiers were unstable unless you used their cable. And their cable was not pleasant used with other amplifiers. Other than that, a twisted pair is hard to beat to reduce noise pickup.

its a double edged sword.

Ideally the greater the spacial seperation between the conductors, the lower the capacitance (good)

but the closer the conductors are wound the better the interference rejection (good)

pick your poison.

generally speaking per my electronics professor, well built amps should have been designed to deal with high capacitance anyway so it shouldnt pose a problem.. or does it?

You can engineer with capacitance, you can't with interference
I know what I would pick
