Shunyata interconnect cables experience

Just a general question, does anyone have experience with Shunyata interconnect cables? RCA's. I am not talking power cables, but interconnects. I know their reputation in the power side of things. 
Reason I am asking is I just received their Alpha USB cable for between my Innuos Zen mkIII and Chord Qutest and I am pretty darn impressed with what I am hearing. I am replacing a Cardas High speed USB cable (the one with the double run of cable). The Cardas is a nice cable, but this Shunyata Alpha is just stunning, now I know its about 3x the cost, but I just hear so much deeper into the music. It has such a black background. Its very detailed yet very refined, hard to explain, its just more natural and musical. I have Shunyata Venon power cables, the NR V10 and NR V12 so I was already familiar with their quality and reputation on the power side of things. This was my first experience with any type if component cable.
So it makes me curious if their interconnects provide the same type of results? I am running a pair of Cardas Clear Cygnus between my Qutest and Primaluna. The Cygnus is a nice cable but now I wonder after trying the Shunyata Alpha USB, what am I missing with the interconnects?
