Audio electronics is one of the simpler branches of engineering.

Agreed - as long as we are talking engineering, and not black magic :-)

To each Engineer his own specialty will look simpler than others.

Totalmente de acuerdo!!! My specialty is steam and fluid systems. Though only 3 yrs in college, I have been designing, consulting, and selling to pharmaceutical, power, biotech, agricultural, utilities, and chemical industry since 19 yrs old, until three years ago (I'm 44); a commercial developer these days. Electrical or sound not my cup of tea, but that is why I got you guys as consultants...

Turn in your silver at the pawn shop and use the money for something that matters. Inside the box? Yea 24 Ga is fine. I prefer stranded. (phone cord) My powered subs? Well OK, I have 12 Ga stranded there.

After years of experimenting, I find I use either old stranded copper 300 Ohm twin-lead or 16 Ga zip for my external speaker wires. Money saved on snake oil is better spent on better drivers and crossovers. You get real improvement going to the 12Ga 3mH coil from the 18 Ga.

Geek, I don't pay for snake oil, I build my own cables. I got the pure silver wire wire for free, I made a pair of RCA interconnects that sound very nice. The only thing I paid for was teflon cover for the wire that I purchased on EBay, it was cheap. Anyways, I will use some Cat5 that I have at home.

Silver + teflon = triboelectricity?

I wonder if I should try measuring the cable capacitance of the multistrand CAT5 speaker cables?
All the different versions of twisting and plaiting and paralleled sets must have some effect.

Has anyone posted results before?

If CAT5 has to have the same impedance and velocity ratio in each pair then each pair must have the same capacitance.

each separate pair should have ~110ohms characteristic impedance.

But bundle 8pairs in various combinations and that characteristic impedance will probably change. In particular the capacitance from all the signal cores to all the return cores will increase substantially.

Will the change in inductance and the change in resistance also change to hold the characteristic impedance as a fixed constant?
Note that Marce was not sure about predicting combined impedance when responding a few posts back in that other Thread.
