Hi
I've had the Gemini in my system now for a few weeks, at first it was a bit rough sounding but it had a bigger more open soundstage than my other cables, (Locus Polestar, Moon Audio Blue Dragon, and King Rex ), it took about 30 hrs too smooth out, so give it a chance to burn in.
In comparison to my other cables, i would say its better in nearly every way, its more extended in the treble, bigger more airy soundstage and fuller sound overall.
i am borrowing an iusb pwr to try soon, will be interesting to see if it makes any difference
using it with my AMR dp777
