Hi Renaat,
not heard the Indra, but tested the Varidig Sextet, which is the digital cable of Stealth, developed to equal the Indra interconnect. I can say that I have never heard a better digital cable than this Stealth one, and I've tested a lot, e.g. Nordost Valhalla - Purist Audio Design - Audio Note - Siltech, etc, etc, etc. Although it's a lot of money, it's worth every cent!!
