I bought the viablue sc-2 speaker cable as un upgrade to my 30 years old Monitor Cobra Cable 4mm. After a few days I switched back to my old cables as I was not convinced the ViaBlue sound better. On switching back I found my old cables are are better in revealing details across the spectrum. I tested some more playing audio test tones from Qobuz. The ViaBlue were not able to reproduce the 30 Hz tone but my old cables were rock solid. Some critical music listning also revealed less spatial information with the ViaBlue.
The cable is sturdy yet flexible. No complaints in that region. Sound wise however they are a disappointment.
