Pre/Power Jumpers for McIntosh MA-7000?


I have been reading that the jumpers from preamp to power amp on the McIntosh MA-7000 are not of great quality and a upgrade set of jumpers makes a huge difference anyone familiar? Have a recommendation ? I read even a average upgrade set will work wonders. Ideas? Help? 

Thanks

Audioquest only makes 1 pair of jumpers at $29.95.  I bought them from Audio Advisor.  
Im not sure if it is lack of shielding on the factory jumpers or just a new clean connection but  a set of low end jumpers really cleaned up and smoothed out the music on my ma6900. I also tried a couple pairs of 3' interconnects with the same results.
