Speaker Cables...Opinions....

Will be setting up 2 Plinius SA-102 in bridged/mono to power B&W 802D's. Any suggestions for a good cable match? My preferences lean toward detail and dynamics to feed my rock addiction, both digital and analog but jazz manages some play time as well. Love a good piano player. I am planning to biwire, maybe 2 separate runs per channel. Significant improvement over internal biwire? Plinius has 2 sets of binding posts so I assume this is a plus..... Thanks in advance for any advice.....

Rest of System:
Basis 2001-RB-900-CJ EV1
Theta Jade transport-DCS Delius and Purcell (pre firewire vers.)
CJ 16LSII preamp
Synergistic Research cables...(may change these as well...not thrilled with the
mini-coupler situation)
