Shunyata Sigma V2 Speaker Cables .....your sonic impressions in your system(s)

Hello fellow Audiogoners - I would be interested in your opinions on the sonic merits good and or bad of these speaker cables. I have heard that the V2 version was an improvement over the V1 version but curious as to what owners of these cables think. I would not be interested in a conversation about the Shunyata Sigma interconnects at this time as I do currently own the Shunyata Omega interconnects. Unfortunately the Omega speaker cables are out of my financial reach as this is why I am interested in the Sigma V2 cables. Thank you in advance...... .
