I use Kimber Select 1020 interconnects and KS 3033 speaker cables. These cables work well with a variety of systems, but I think they're particularly good at bringing forth the harmonic magic that makes Cary equipment special.
(My system: Cary CAD 300B amp (push-pull design with 4 300Bs), JM Lab Daline 6.1 speakers, Melos MA-333 preamp, EAD Ultradisc 2000 transp. & DSP 7000 Mk. III dac, SCE HRS, VPI HW19 III turntable w/Premier FT-3 arm, Benz MO9 & Melos phono section.)
