This may be a silly question but...

Paul Klipsch supposedly used to say that lamp cord was good enough.....

So does OFC have sonic benefits or is it just the least resistance that makes it better?

Loving the history here - let's not forget that McIntosh for years said that zip was all that was required...

Since Rsjb poses a sincere question which has bedeviled us all, IMHO audio is a game of inches. It is also highly cumulative - the better each part is, the better the sum should/will be. This is of course the elusive synergy.

Put it this way: if you can get Romex to stay on your binding posts its probably worth a try...

I made some speaker wire a few springs ago, just as a project. I used 10ga wire, typically used for dryer cable, and made biwire cables. I though they sounded better than my blue heavens (perhaps fathers love?)...however they were later replaced by some fine MIT's...

It's funny you should bring that subject up but a friend and I tried some Vampire Wire 10 gauge hook up wire and we both canned our expensive speaker wire. This is the Continious Cast Copper wire that comes in two colors black and red. Michael Percy and a couple other places had it in stock but I should have purchased more of this. Vampire Wire still stocks the 18 gauge wire but the 10 gauge is pretty good wire and may breath new life in your system. At least it embarrased the expensive silver wire I was using. It may not do this in all systems. And the cost is under $3.00 a foot on last check.
