What would be a good but not silly money mains cable to use with my Bel Canto Evo 6? I've a Nordost El Dorado which I'm using with my Bryston amp. My other electronics are fed by a 1kVA Ben Duncan Pure Power on a different socket on the same circuit. Would the Bel Canto respond well to a bigger e.g. 2kVA isolation transformer?
