Best cables for Luxman

I own a Luxman M-600a series amp, C-600f preamp, D-06u CD player, Clearaudio Ovation with Tracer arm turntable, Kiseki Purpleheart cartridge, Shunyata Denali power conditioner with Alpha NR cable. B&W 802 series 3 speakers. Interconnect cables are Analysis Plus Silver, speaker cables Big Silver. I'd like to improve the heights. Your thoughts would be appreciated.
