Speaker cable for BW Nautilus 803


I have bw nautilus 803 driving with ML 332 using coincident cst1 speaker right now it is very good but something is telling me that it can get better looking for pair of single bi-wire speaker cable, current IC is acoustic zen silver and matrix reference souce is Cary CD. Looking for something that is warm and sweet. Any recommendation will be appreicated.

I've got the Audioquest Caldera bi-wire on my N803s and am very happy with the combination. The Caldera is smooth and detailed without getting grainy or bright and has a very balanced sound with solid imaging.
Blackie, what are you driving it with amp and pre-amp source thanks for all the response
I've got a Clearaudio Champion TT and a Linn Genki CD going into a Placette Passive Line Stage (all connected with AQ Viper) and from that into a Rotel RB1080 (next on my upgrade list) to the Calderas and N803s.
