Mike, yes I am going to keep my tg audio SLVR, as the matter of fact, Frank will upgrade them with furutech rhodium IECs. But they are on my front end - cd player and pre-amp. For the amplifier I would like to buy AC cable that will handle better high current demand of my amp from the 20 amp dedicated line.
Open up your amp and take a look at the wire running from the IEC to the power tranny. Then take a look at the wires that make up the power tranny. Using anything larger than those is a waste current wise. In fact, I bet I can say the same thing about the 20 amp circuit.
HowdyIt depends on how much heat you are willing to deal with, as well as whether the current is continuous or not, etc... (see http://www.powerstream.com/Wire_Size.htm for example and compare the differences between the "Maximum amps for chassis wiring" and "Maximum amps for power transmission" columns: for 12 gauge it's 41 amps vs. 9.3 amps.)
As far as listening, well 10 gauge wires for my dedicated circuits allowed my system to sound much better than the 12 gauge they replaced... (Yes my amps have big wire :)
So how do you differentiate between a 6' power cord and the wiring of the power transformer to which the power cord is connected? Seems to me, that they'd both be on the "power transmision" side of the equation, no? Therefore the power / current requirements for both are the same. And that's assuming that there isn't a dinky power fuse in between.
I'm not arguing that 10G wiring doesn't sound better than 12G, I'm just arguing that the reason isn't current capability.
HowdyNope, it's the length and hence the voltage drop over that length. This is true for a pure sine wave, but even more of a problem with varying loads where the instantaneous current exacerbate the differences.
You don't typically have, say 6' of wire between the IEC inlet and the power transformer, this wire is in air and hence can cool easily and it's short so any voltage drop is correspondingly small. The wire on the power transformer is in an entirely different circumstance (i.e. it's a part of a transformer :) and calculating the safe current is more complicated.
Just go to your local store and check out the power cords, as you get to longer and longer lengths they use bigger and bigger gauges for the same current (or wattage) rating.
