"It's probably refered to litz braiding as it's done with litz wire "
...i'm still not sure what you mean. do you mean that this braid uses litz wire?--well, like i said, neither Cardas nor Kimber uses real litz wire, even though they claim to. i have read what they said, and they are wrong. just cause they're big companies doesn't mean there's some snake oil in what they say.
and no, i haven't a-b'd the plugs. i just read the description on their web site which someone showed me. the logic behind it is flawed. that's all i'm saying. the thing is, i personally don't think any human can hear the difference between this and that plug. but like you, i always want the best...... so, if you're saying that these plugs are $15/each and are copper, well, then i'd agree, they are good deals for what you're getting. however, i personally wouldn't use them just cause they make no sense. but if you don't care about the science behind them.... $15 for a copper plug is a darn good deal. yes.
