Zavfino Arcadia is an ok cable. Nothing to write home about. I would say it’s a little dull sounding. The Neotech is silver plated copper and sounds a bit more open. Between the two I’d say Neotech is a better choice but depends what connectors you have on it. Decent gold plated RCAs should be fine.
As an alternative, I would recommend Audience OHNO interconnects. I think they’re better balanced over all.
