To add a data point, Norne Silvergarde S3 cable (20 AWG x4 OCC silver litz) sounds majestic with 1266 Phi TC. The usual worries regarding pure silver cable sounding too bright, lean, whatever goes out the window here. Compared to JPS stock cable (which is awesome stock cable), Norne gives you more detail resolution while being smoother. Bass is fantastic also.
