Choice of Wire for Dedicated Line

W,
I resell Belden 83802 for dedicated lines ($2.50/ft first 25 ft, $2.25/ft above....)
It's 2x12AWG tinned stranded (7x20AWG), in FEP, twisted pair in FULL shiield, then in a nice red, slippery, thin outer jacket. Threads easily through walls, and isn't too stiff. Fireproof, too. The shield twists up to a nice beefy 12AWG ground.
Makes GREAT PCs, too, for which I assemble DIY Kits for $32 ea. RSVP your needs. This is VERY FINE commercial wire that performs admirably outright, and stupidly-good value.
RSVP your needs.

Lak,
How long did you burn-in the 83802? The advantages of Teflon over PVC should become more apparent over time. I trust your front-end is resolving enough to yield a perceiptible difference.
My order of preference:
1. 83802 (12AWG)
2. 10AWG Romex
3. 12AWG Romex
Something about a quieter background yielding greater perceived dynamics, especially at lower listening levels.
Its as though subtle details are more discernable, so that loudness doesn't have to be increased. In my case it means more satisfaction in very late night listening sessions....
Red, nice to bump into you again. Is there a "thanksgiving" analog in kiwiland?
I agree with you that setting up dedicated lines is primary, but if you ARE going to do all that labor it seems to make sense to use a finer cable if lengths aren't TOO long, as $2/ft is still a relatively cheap investment toward improvement in our systems. I installed BOTH lines AND PCs made from 83802, and the composite improvement is significant. As to the causation distribution amounts I can't say. I'm getting strong feedback re the improvements in just introducing short DIY 83802 PCs, but I still suspect the more significant improvement lies in using IT from start to finish. I've become a devotee of this red "firewire", and am such a sucket that I'm assembling DIY kits of the stuff with good connectors for what amounts to minimum wage! If some systems don't benefit from it, then at least it's cheap, and it has high WAF when that bright red "firewire" is set in clear 1/2" PVC. Ha.
Keep well, all. Ern

Lak, I do NOT find that the Belden 83802 is directional. ALL the PCs I've made sound the same. Since the cable is NOT marked, I'd imagine that 50% are each way....interesting about the Romex, though.
Red, do you mean that USED Romex sounds worse when reversed?
That I could buy in a hurry.
Cheers.

...swept off the floor at the smelter! A gazillion crystals/inch!

Yup. I recommend Belden 83802/3 for oustandingly pure and noisefree dedicated lines. May NOT be code-approved in all states. RSVP for details.

Hi Stehno. The point is that the cable matrix is well-shielded from outside influence, as you surmise. Re self-noise, it's thought that by using the very best (practical) dielectric (all-teflon), phase, echo, and hysteresis-like distortions are minimized too. Here in Boston we have a very stiff power grid, and perhaps my dedicated 83802 lines are unusually quiet without further enhancement. It's pretty clear that the noisefloor dropped after I introduced these lines and PCs vs the old Romex and other PCs (stock, Absolute Chinese, Belden 19364, Harm tech ProAcC11, and VD P3) I had on hand. No cable can FILTER out noise, of course.
But sly devil's advocacy can be fun, eh? Cheers.
