I have owned both of these interconnects. The AQ Sky is a very good interconnect, but the Stealth Indra is one of the top two interconnects I've ever heard in my system (the other being the Jade Hybrid Gold). The Indra is very articulate, yet never edgy like the Nordost Valhalla. Very natural sounding, but with stunning resolution. It comes about as close as I've ever heard to meshing musicality with transparency from one cable.
