I was looking for the same things for a long time and all I was able to find were the audioquest and taras mentioned here. I was gifted a pair of tara lab interconnects so I just took my old Homegrown Audio Silver Lace interconnects that I was originally using and used those for the jumpers. The tara "missing link" as I believe it is called would have neen the way that I would have gone had I not been given the new interconnects. Really, all they are is really short interconnects so $40 or so isn't all that bad for the upgrade.
