For Ozzy and others who found the Fidelium's did not work, have you tried other copper foil cables and had the same results?
It could be a tube/amp/speaker mismatch problem. Large thin foils have an electrical characteristic (either high/low capacitance/inductance, I forget which) that just does not play well with some amps and speaker crossovers.
