I have these QED Genesis Silver Spiral Speaker Cables with jumpers for sale which are 4m in length, they are terminated with QED AIRLOC forte banana plugs at one end and QED AIRLOC spades at the other, the jumpers are terminated in the same manner with QED AIRLOC. They are in very good condition as can be seen from the photos.

These have been QEDs top cable for many years, and are very good. To my ears they produce a very open and detailed 3D soundstage with great separation. Bass and low mids are tight, very good top end frequencies.

What QED say:-
"Audiophile-grade speaker cable, by QED. This award winning Signature Genesis Silver Spiral is the result of over 40 years of scientific research and development into loudspeaker cables. Silver Spiral's exceptionally low resistance allows amplifiers to exert outstanding grip and control over the speakers they're driving, especially at low frequencies. This isn't just another speaker cable it is a high-performance audio component representing the culmination of QED research and development over the past 40 years."
