for your opnion theorically what is the cable that can sound better compared to all 5 cable considering the connectors and the cale quality ?

I suggest that you make your own. Furutech FP - S055N cable with Furutech NCF rhodium connectors will help alot with your bass. It maybe a bit more pricey than what you were looking at, but will be much better.

@marco777 find a reliable distributor and buy bulk Furutech FPS-032n cable with Furutech F-11 (Cu) copper plugs. Terminate it yourself or pay the distributor to do it.

Or wait until an FPS-032n shows up on ebay. 
 

I bought 2 SHUNYATA King Cobras PCs. Excellent for bass. But they are pretty rare and hard to find.
