Hook-up Wire: Duelund DCA16GA vs Neotech STDCT-16 vs Cardas 15.5 AWG


Hi guys.
I want to replace the wire in my speakers. Who had the experience of comparing these wires?
Duelund DCA16GA tinned copper
STDCT-16: Neotech Multistrand Copper
Cardas 15.5 AWG copper multistrand
Tell me which copper wire will be better for sound? Maybe you have thoughts on other hook-up wiring.

Sorry for my bad English.

Granny, I’m close to the jumpers for my kef r900 speakers. 

Shhot me a quote, please. 

Do you need a photo of the cabinet rear?

i do not bi-wire. Thanks
@grannyring So if you're bi-wiring, say, with 16 and 12 awg, it's better to twist the two 16's together and the two 12's together (tweeter separate from woofer), rather than 16+12 and 16+12 (positive separate from negative)?
Hi Granny!
My friend has speakers on (2хSEAS H1215 + SS 15M/4531K00 + Morel ET 338)
This is a crossover circuit.
Now he uses the Analysis-Plus Bulk Hook-UP the cable Analysis-Plus Oval 12.
Which cable can you recommend which will be better than Analysis-Plus?
Thanks.
Has anybody tried new Duelund 600 volt Cu-Sn 12 AVG and 20 AVG cables?
How do they sound compared to regular Duelund DCA20GA and DCA12GA?
