Belden Bi-wire 1810A speaker cable

My previous speaker cables were QED Original with Nakamichi banana plugs that I've ordered from Amazon UK. I was satisfied with the cable for quite some time with my previous Bowers and Wilkins 685 s1 speakers as I didn't use Bi-wire feature on them. Many people mention they sound better on single wire and I wasn't too eager to try different.

However, when I changed to Nautilus 805's , I realize I only have Bi-wire terminals on speakers without jumper cables so I decided to do some online research about speaker wires and also some of the experts I know for the opinions.

 One of the biggest experts in Hifi and audio that I know is my parent's friend from Croatia (Mr. Miro) and I quote his reply ;
"When it comes to speaker wires , they do make a difference to the sound. Wires have resistance that should be minimized but also they have inductive and capacity component which do not have great effect with smaller lengths. Cable should not be rolled (inductive component) or too close in parallel (capacity component). You should take minimum 4mm2 wire. "

 Another advise on which cables to buy I got from Mr Colin who is running his own company in Singapore setting up professional studio equipment ;
"Bi-wire and single wire give us different effect.Bi give you maybe more stage feel and single maybe more musical...for project installation we always use Belden or Canare audio cables."

This advises have greatly narrowed my choice and I found a shop in Sim Lim Tower selling the mentioned Belden and Canare cables LHS Electronics Enterprise .
Mr Robert from LHS was the sales who helped me find the cable. I decided to go with Belden bi-wire 1810A.
I recommend this shop ,service is excellent. I wanted about 30 mins for uncle to fix all the plugs and spades on the cable ends. He did it very professional.
Sound using Bi-wire really makes a difference on n805 speakers! It's quite 'stage' sounding that I like because I listen to lot's of electronic music. Sound with this upgrade seems to be crispier a bit more accurate with slightly lower bass extension.
Reason why I decided to go for Bi-wire and 16 connectors is in case one day I decide to Bi-amp the speakers. I 'm very pleased with my purchase, money well spent! :)
