You seem to think that replacing non-RoHS cables by RoHS cables constitutes an upgrade but the reliability of lead-free solder is lower rather than higher. > The main variables I've come across seem to be gauge thickness > (e.g., 12 or 14 AWG) and shielded/unshielded.

Seeing as 1,5 mm˛ wire is commonly used for 16 A circuits, 0,75 mm˛ should be good for at least 8 A. At 230 V, that's 1840 W. Shielded mains cables would be most beneficial to people who have low amplitude and high impedance signals nearby. Eg electric guitars. Probably not worth paying for unless you already have a hum/buzz problem AND it has been shown to come from the lack of shielding of the mains cables AND it cannot be solved by simply keeping the signal cables away from the power cables. > I'd also be curious to know if anyone has any specific brand > suggestions.

My only suggestion would be to not fix what's not broken and worry about the next item down the list instead. :-) -- André Majorel http://www.teaser.fr/~amajorel/
