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.

Thanks grannyring! I’ll try the Duelund wire.
Speakers crossover don’t have contain resistors.
I use Soviet СМ capacitors. Inside the конденсатор СМ is a high quality tin foil in oil.
They have long been discontinued, but they are very good capacitors . My friends and I compared the СМ capacitors with Audyn True Copper Max and everyone liked the СМ capacitor more. Despite their age, they sound great.

Sorry for my 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)?
