Inexpensive things for audio that work

For internal wiring of speakers: Cat6 solid core. The advantage of solid core is that you can strip it with a sharp knife very easily, and it can be put through the lugs of any speaker, and when you are experimenting it can be easily secured by twisting the end back round (no need to solder)
 
Correction Midrange, I was an advocate of Cat 5/6 cables
use it even to make power cords but after reading a article
curiosity got the best of me so have to try. Believe it or not
best bang for buck, WE 16awg cables, couldn’t get those so
had to spend a little more to buy Duelands 16awg instead.
This is a must try for everyone for speaker wire & speaker
internal wiring

I would add caution to using non approved cables for power cables. Hell I wouldn't ever go there. Fire protection is serious stuff.

There are rules regarding fire retardant powder inside of power cables. if you use cat5/6 leftovers you are taking away that protection.

Could be an insurance hook.

POE isn't really that much different. But, yeah, I'd not be doing mains on CAT5/6

I'm glad you won't. But let's review the numbers to dissuade others from trying this.

Yes, thin wire will carry enough 120/240V to power preamps and many power amplifiers. When working right.

But wiring must be safe when things go WRONG.

PoE is power-limited, 10 Watts up to 90 Watts. You can NOT get more power than this.

My wall-outlet will supply around 10,000 Watts for a second, 2,300 Watts all day long.

That's 25 to 100 times as much power. Or roughly between a butane cigarette lighter and a large propane plumber's torch. I can start a fire with a lighter. It is much quicker with a flame 50X bigger.
 
Thermal strippers used to be required for military work.

No clue about today.

Always wanted one.

There are some on the bay now (I just checked). There's one at $50 but it's not working (and I suspect isn't repairable). Several of a different brand that look ok in that range, too. If you go there, make sure to search under both "thermal wire strippers" and "wire heat strippers".*

*probably not just "heat strippers" or "hot strippers" or you'll likely get something else 🙂
 
The other issue with CAT-5 or any comm cable is it does not have insulation designed for high voltage. It is designed for SELV/PELV rated power sources.

You risk serious fire and damage if you use it for mains low voltage applications.
