Interconnects & XLR cables for Bryston Amp/Preamp

I have a Bryston 4B ST amp and BP 25 preamp. After getting great information on some ZU Wax speaker cables form the Audiogon participants, I was wondering if there are any suggestions to bring out a little more detail using interconnects and XLC cables. I have Synergistic XLR cables and various interconnects. I have a Meridian 508.24 CD player. The ZU Wax improved the detail and dramatically opened up the sound stage so I am just trying to squeeze out a little more. Any suggestions?
