So far I like the SuperConductor 3 speaker cables quite a bit. The sound stage seems larger, more 'bloom', more layered, with better decay, and better detail than my DH Labs Q10. The highs are extended and sharp when they should be, but not bright or fatiguing. I could live with this speaker cable on my Magnepans. Like most JPS cables, they are STIFF and unwieldy, but since I leave them put once I make the choice that doesn't concern me too much.
So far I am not getting positive results with the SuperConductor 3 interconnects; they seem a bit etched and bright to my ears as compared to my older SuperConductor + cables. I definitely hear more detail with the 3's but I also hear more background noise and the etched sound is not worth the extra detail; most likely not the right cable for my rig, but I am going to play them some more just to be sure.
The Kubala Sosna cables sound very good but they fall on the other end of the spectrum, definitely on the 'warm' side of neutral. Not sure however if I like all this warmth either; more listening is required. One thing that I will try is using the SuperConductor 3 speaker cable with the Kubala Expression interconnects and see how that 'balances' out the tone.
Still working on this!
