Yes I have.
To my ears and in my sistem stranded CAT5 sounded more harsh in upper mid region.The top was somehow agressive.Similar result as with stranded telephone wire.As I can remember there was not much difference in bas between stranded and solid CAT5.
Solid core CAT5 cables sound quite good comparing to other so called hi-fi cables I've tried - for example: Nordost Flatline Gold, QED Silver cables (similar to profile silver 12 - discontinued), Transparent Audio (can't remember name-they were not cheap) and a few others.
I have solid core CAT5 (two 0.5mm wires per loudspeaker) in my sistem for over a year with no need to replace them.

A twisted pair is always the best minimum choice for internal wiring. Preferably solid wire.

In my experience Cat-5 is not brittle at all for that purpose and provides "ready made" twisted pairs right away. Never snapped a wire from it.

Though better copper or plating or dielectric might be interesting too.

Isn't the Cat-5 made from solid-wire pairs, by definition? I never saw a legitimate Cat-5 cable with stranded-wire.

There are teflon sheated Cat-5 if I am not wrong too.

THIS IS ALL FROM MEMORY:

Category 5 cable is 24 awg copper wire pairs with N twists per unit length (I forget the numbers), having a nominal impendance of 100 ohms (I think).

Category 5 cable designed for use in TIA/EIA 568-A/B wiring has four pairs, has a sheath diameter of at least 5mm (I think), with the minimal safe turn radius for 100 MHz operation being no more than four times the sheath diameter.

Category 5 cable may be either stranded or solid, the specification doesn't say other wise.

[Note: I haven't read the relevant specifications in about a decade, and I don't work in that field any more]

----------

In practice: 100m Boxes of cable you buy are solid. Patch cables you buy are stranded. Stranded patch cables are much nicer to work with in a crowded rack, but they are a real pain to crimp yourself.

Cat5e Plenum (such as Belden 1585A) utilizes a teflon jacket.

Dave:

Cat 5e Plenum MAY use a teflon jacket. I have no doubt that a lot of it DOES.

But -- there is no guarantee that it is teflon, unless it says so on the box. A plenum rating merely indicates that it's more fire-retardant than FT-4 (and safe for use in plenums without conduit). I would expect that spraying an appropriate fire-retardant coating on regular thermoplastic would meet the specs.

(Again, caveat reader -- my memory's not as good as it used to be).

I have 4 different types of CAT5 cables:
-26 AWG Shielded CM 75C UL 100MHz (stranded)
-24 AWG 4PR CM75C 100MHz (stranded)
-24 AWG 5 EC UTP 4PR (solid)
-R&M Freenet Enhanced CAT5 125MHz 4x2x0.5mm (solid)

I use Belden 1585a. I got a 1000' spool from ebay for
$39. I'm using a double strand for the signal and am
using 48 strands from the output to the terminal.

My speaker cable is also made of braided (27 pairs
per side) Belden 1585A (Chris Venhaus).

I find the wire very good. I really like HomeGRownAudio
Silver wire but it can add up to be a lot of money.

You need to parallel many Cat5 wires on the output to
get a good bass.

Best thing is to try.It depends on how much current ludspeakers are drawing.
I only have one wire(0.5mm) for + terminal and one wire(0.5mm) for - terminal on my full range loudspeakers.

Please define what you are talking about when your saying from the output to the terminal.. Are you talking about the internal amplifier wiring?
When you are talking about "to get good bass" are you talking about the wire you use from the amp to your subwoofer?
