Hi Porselen,
I use the Gryphon Colosseum stereo (dual mono).
I use PAD Dominus/Anniversary Contego Cables on everything except: Gryphon VIP Reference PC on the Gryphon Colosseum...in addition to coming with the unit when i acquired it 2nd hand, and also to being 20amp and manufactured by Gryphon, it also fits underneath the unit (a PAD cable would not). I also use Sablon Audio Gran Corona on Oppo and Velodyne...exceptionally good and extreme value for money.
I just competed my cable upgrade. Jena Labs Twin 19's on the speakers, Purist Audio Proteus Provectus interconnects and Purist Canorus power cables.
