Thank you for your input. Went to local hifi store, choice of chord, QED (exact model not sure), or the standard $3 pm, which is what I have. Assistant said the QED with silver would make my Dali Helicon 800's even brighter (whatever..). The chord has the extra insulation. Not convinced. So standing still.
Like the Van Den Huls, (always trust the Dutch) but pricey, like the concept of the RG13/U doing fine at only $3.50 a metre. But then my existing cables were $3pm. Will stare at my navel a bit longer. .........
