On Friday my new Sigma XC arrived to power my Denali 6000 V2, replacing a Sigma NR V1. I am amazed at the improvement this cable brings to my system. Someone already explained it in other places, but really the sound is much CLEANER, you listen to micro details that used to be more difficult to hear, or you just didn't listen. The orchestral sound is wonderfully dense and heavy, but liquid at the same time, it is crazy and above all it allows me to increase the volume (almost asking me) without it becoming congested. I don't know when I will be able to do it, but I know inevitably I will have to change my Sigma NR V1 for V2, it is simply useless any resistance.
