Short piece of spk wire sustitute for spk link?

It's been suggested to me that the best jumpers use the same wire as the cables (where possible) to maintain the impedance etc. Not sure if it makes a difference, but anything is better than the stock jumpers. I've tried expensive custom jumpers with spades ($180) and a bare ended bit of audioquest cable and both worked about equally well. A tight fit should eliminate the need for copper cleaning over time.

Try the ribbon jumpersfrom Mapleshade. Unbelievable boost in speed, clarity, and resolution at $25. I use the ones with the PLUS upgrade for a mere $35/pair.

I am using Cardas jumpers [both the bigger and smaller ones] and lengths of bare wire. Plain Romex is better than some of the stock jumpers in my system and dirt cheap; I have been using some 14 Ga. 99.999 silver wire from VH Audio, running both single and double ones. I don't know which you will like better but there is a considerable difference between the Cardas and VH in sound.
