Speaker jumpers

Almost all stock jumpers are brass. All inexpensive audio equipment wiring, connectors and inputs are brass. Which is a main reason why they are inexpensive and sound like crap. You should at least upgrade to copper jumpers. And even a *single* strand of minimally thick 99% copper wire will improve the sound and clean current flow 100 fold. A single strand!

I just went through this about two weeks ago. I have a pair of Sonus Faber Amati Futura's and just tried Transparent Audio's jumpers and to my ears they were worse. I'm sticking with the ones from Sonus Faber.

What type of jumpers does Sonus Faber provide ?

I very much like my Transparent Ultra jumpers 

On my 805's and 803's I was happy with the stock jumpers and very inexpensive cabling throughout until my mocking "audiophile" friend loaned me some Nordost speaker cables. Different, not necessarily better, but certainly different. So now I have several thousand dollars of Nordost cabling everywhere, and the results.... different, I'm unsure if necessarily better.  
Now I ask folks what kind of cabling they own before I ask them over, and please, no offers to loan me magical power cords, interconnects, or whatever.  My clarity on better and different is a sliding resource and it's better for me to know that than going to the bank.
