Kubala Sosna Cables - Reality Check
I am auditioning some of the Kubala Sosna Expression interconnects and speaker cables. My initial impressions are that these wires are a bit to the 'warm' side of neutral. (Not complaining or criticizing the cables - just making an observation). Have you gotten similar impressions in your rig with these cables?
