J-Fkn-C... the input impedance into modern amps is 10k to 200k ohms.
(a 26 gauge would be overkill.)

“skin effect” would be a better argument for one gauge over another... and that would support a smaller wire as well.

but maybe he is right... (it would not be a she to make such a claim)

Isn't "skin effect" the reason audio cabling in general has smaller and more numerous strands than the same gauge standard wire, less depth+more surface area=less inductance?

Just made these because that’s what i had on hand.

Will it sound a whole lot better then these probably not, but at least they will be cut to length.

Is that coaxial cable? If it is, the 12 gauge sizing is likely the overall diameter, which makes this discussion pointless. If not, let us know if you get any noise. Twisted pair or coaxial is the best construction for rca cables in any case.

Not the op, I presume he has 12g speaker cables or something

the ones pictured look far smaller than 12g especially considering he has two cores in that little 4mm diameter bundle with dielectric as well

Oh damn, I got lost.

Yes this is what the guy was telling me but I need you to dumb this down a little bit for me so I can understand better of why this is bad I want to understand

Capacitance blocks bass, inductance blocks highs.

 

[ckirocz28]

Thank you that’s what I was looking for to understand

They both exist in all conductors in varying amounts and ratios (relative to each other).
If you look at a passive crossover, the coils are inductors that block (reduce) highs, and the capacitors reduce bass.
So, for a cable, you want as little inductance and capacitance as possible, within reason. Whatever you do, don't coil up your excess rca cable length while you're using it, inductance goes up pretty quickly in a coiled rca cable, your highs will just go away. But then you are building your own cables to avoid having excess.

Even in twisted pair cables?
or in Coaxials?

Even in twisted pair and coaxial. Recently tested this with DATSv3, accidentally.

This is good information to know honestly. Well if this is the case then I might as well go back to my original plan and just buy some stager silver solids. Yes it’s expensive but I am also building a expensive system. And yes I even have a limit of means but I’ve already invested a lot of money and those silver rcas have good reviews. I’ve been wanting them just was still deciding on routes to go between klei absolutely harmony or wbt silver rca connectors. Those are all expensive no matter how you look at things. I guess I’m getting to the point where I’ll have to order some eventually just deciding things is the deal for me. I was hoping to use my wire but with the understanding of having a balance now for size it’s best I got with the silver solids.

Don't waste your money on those super expensive cables! Just get good quality cables that are made well, the biggest difference in quality is in the construction and reliability of connections. Just don't buy the cheapest you can find.
I ran Stinger 4000's but they had breaks in connection inside the connectors (solder?), other than that they had excellent signal quality. I switched to custom made cables that are equally excellent, but with rock solid connections.

What is the mechanism causing this?

I am pretty sure that the inductance formula has the area and number of turns being the main contributors. And in the twisted pair that area gets reduced from the pairing... and then reduced more with the twisting.

Coiling the wire, just like an inductor coil, predictably produces the same effect in any rca cable, maybe not as much as stardard wire though.

 

[ckirocz28]

A twisted pair effectively makes it not work like a coil anymore.

If you had each 1/2 of the pair coiled, and even better around a ferrite core.. then it would become a choke.
As it is... the twisting of the pair, makes the coil area become zero.

I'll have to test it again and post the results, probably Thursday.

 

[ckirocz28]

The easiest way would be one set of RCAs into a summing (differencing) amp, and the ones being tested into the side of a differencing amp.

Then one gets the difference between the two setups.

I've got a DATSv3, that's how I tested it before (measuring inductance, capacitance, and impedance), but that was just 1 rca. And I forgot to do the test this week, maybe in the next few days.

Here you go. I didn't have a spare 12 foot coax rca so I just tested the Stinger 4000 series 12 foot rca's (twisted pair). The coils were about 3.5 inches in diameter, so about 13 or 14 coils. The first picture is with the cable straight, second is coiled, third is coiled but tested in a way that simulates a balanced signal (clips hooked up to center and ground on one end, cable shorted at the other end). The third picture is the one that shows the benefit of twisted pairs, but that only works with balanced signals. Inductance is shown top right of the T/S specs window.
