Those are called jumpers and some cable manufacturers make them, Audioquest I think. This may make a significant improvement, there are threads here and/or on Audio Asylum that discuss the immense improvements jumpers like this make for the highly reviewed Creek 5350 SE.
Alternatively, there are small cable makers that advertise on Audiogon that might make a special order set for you.
Good luck,
Arni
