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!

Well OP you got every answer possible--they won't make a difference, they may make a difference, and they will definitely make a difference. FWIW it is a hobby...spend a little money and see what your ears tell you. No one else posting here is going to live with your system.
BTW I agree with adg101 and akg_ca: better cables with jumpers rather than two sets of lesser cables. YMMV--as you can see from all the different opinions.

Elizabeth, the cables only need to be 6'.

Astewart, yeh, I sure did... It's like being on one of my watch forums, lol. 

Im gonna bite the bullet and get a set for $2-300 and a jumper. 

Thank you again, everyone. 
I’ve owned both the 4tc and 8tc and good cables but there’s so much better out there and one doesn’t have to spend a lot to hear it.

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..
