Cables with Musical, Deep, Tight, Bass Response

Hi!

Can anyone recommed a speaker cable to run from my amp to my active crossovers, again into my sub-woofers (per REL; Von Schweikert) and again from my mono amps to the bass portion of my monitors. Can you also recommend interconnects to run from the variable out on my amp to these mono amps?

I am using a Denon 3910 CD player through the old DK Design Mk II interconnects into a DK Design Mk III through a pair of Guerrilla Audio silver speaker cables into the top portion of a pair of LSA2 speakers and need a recommendation for speaker cables to go into a pair of RBH SA-400 active crossovers, the same to go into a pair of TBI Magellan VIII sub-woofers and the same again to go from my NuForce Reference 9s to the bottom portion of my LSAs for the purpose of bi-amping. I will be coming from the variable out of my DK and into NuForce Reference 9 mono amps with the recommended interconnect. I will be running my monitors full range, bringing in the subs at, perhaps 40 Hz.

Any advice?

Thank you!
