I bought this cable new from Wireworld distributor Audio Thesis in 2017 and used in my study rig. It bettered several Audioquest cables, the Phasure Lush, Curious Cable, DH Labs Silver Sonic Mirage, and Wireworld Silver. Fantastic level of smooth non-fatiguing detail and imaging with the widest soundstage I had experienced. Love, love, love this cable - the best USB I ever owned; but due to health issues must sell all but a couple prized pieces that will go to kids.
