Upgrading speaker cables...


Currently, I have a Cambridge Audio CXR200 that has a bi-amp feature on it. I have 1 channel going to lows, and 1 to highs for each side. So, 2 pairs of cables for each side. 

I'd prolly have to go down the line on the cables if I had to buy 2 sets.... So, would I be better off with 1 set of nice cables with a set of jumpers, or 2 sets of lower down the line cables for them?

Reason I'm looking is, I have cheap cables currently, and was told a nice set of cables may open up my speakers (Wharfedale Reva-4 towers) and make them sound better. 

Thanks for for any help/suggestions!

All other things being equal, the longer the cables the more important the quality/gauge. I wouldn't sweat too much for 6' cables. Any good 12awg copper cable should suffice. 
I am worried that your gearit cables are a copper/aluminium alloy, and that the connectors are brass or something..
In which case a new set would be beneficial?

I am in the process of finding a new set with the assistance of a very kind AG member. 

If anyone sees a set, pls feel free to lmk. 
belden 5000ue 12awg (true 12awg). PE insulation and OFC copper, twisted for low inductance.
Cheap and way overkill for a 6ft length - it would be pretty much like no cable at all.
