All very interesting and somewhat entertaining...............b4icu MAY have a valid point concerning what is best or at least better, vs what is PRACTICAL..........As some have already seen, connecting "0" awg to any gear I've ever seen is at the least challenging. They're simply not designed for welding cable, per se, so cable makers are forced by physical constraints to work with what fits, even (possibly) knowing that they could do better.............just a theory............Still haven't tried this myself, as I have other priorities at the moment, but I do plan to give it a whorl at some point...............worst case it does nothing impressive and didn't cost much to find out. Best case, a little money well spent and my system sounds better................We can argue theory, intelligence, credentials, integrity, etc. all day.............Bottom line, as with everything audio, is that you will hear an improvement, or you won't.........It's a cheap enough tweek to roll the dice............How many tweeks do you already have collecting dust, what's one more if it works??
