I own the Indra, NBS black label (expensive, top of the line), and recently tried the Harmonic technology cyberlights. IMS, the NBS was not even close to the other two. I prefer the Indras over the cyberlights from preamp to amp, the other way around from source to preamp.
Components:
SAP J2001 (horn hybrids) biamped with 45 tube monoblocks and EMMlab CDSD/DCC2 as digital source.
