Agree solid not bad, by years have modified all my devices going solid like on PCBs and very old tube gear also had solid wire. Though i still open minded and respect very well people's preference for other choise. For sharing if other like the CAT5/6 sonics but as i like to have screen around cores i attach some good cheap examples. Those can be used as line cables and screened speaker cables if length and power are taken care of.

Cat 6 or cat 7 SSTP are four solid twisted pair each individually shielded. With an other screen around them. They are designed to carry GHz 75 Ohms network signals.
Shielded Twisted Pair Cable (SSTP), 4 pairs, Solid, Indoor, 23 AWG, LSZH, Category 7 (1000 MHz) / Twisted pair cable / Cables / Catalog / Hyperline as an example.

2,3 & 4 of the Canford examples have PVC insulation which does not attract me. CAT 6 has better quality insulation.

The first one DKT-M with foamed polypropylene looks good but I am also fan of Cat 6 - I use it for all my audio work and now we can get screened CAT 7 I think it represents extremely good value for money and I think we will have to pay much much more to get better.

Yes those you link there is certainly speedy monsters and look good. Maybe by mistake i thought of CAT 5 inspired by LC's picture where pair was cannibalized for whatever had surrounded them at a time. The footprint for those i attached can be lighter for mono asymmetric as they are born as such (don't carry 3 pairs more if not needed). The two of them have foil screen+drain wire (little stiff when bending) and the two other have old fashion multiwire screen (most flexible when bending).

You probably right about the isolation quality. I use the Canford products because have had very difficult to find solid core with just two cores and thin diameter to keep skin depth bad for all audio freqs, most cables seem to be multiwire per core. The DKT-M i bought a couple hundred meters on discount and it works for me both as line cable, circuit cable and as USB2 streaming cable (audio). Will investigate those screened CAT7 in future.

I changed internal input cable from coax to twisted pairs app. 3 weeks ago. Measuring the noise floor before/after clearly shows lower noise floor using twisted pair. Even 100 Hz component is few dB lower with twisted pairs.

Just try shielded twisted pair like this:http://www.diyaudio.com/forums/vendo...ml#post3941168.
A there is no current across the shield, it does not inducts noise.
I use one SSTP CAT 7 for the two chanels of each analog sources and preamp ( PU, analog Tape, K7 ) and one for the 2ways of my active enclosures+power on command of the integrated amps. I use fiber for the digital sources <-> preamp.
I changed most of the RCA plugs for mini XLR. for i can change between symmetric/asy with the same cables and plugs.

+one for the volumes control digital commands: I prefer to carry a high level audio signal to keep signal/noise ratio at its best with long distances.

Just my two cents.
