Fascinating thread. It finally motivated me to quit lurking and post something.
I understand Schroeder’s need for a warning on a public forum but I still don’t understand why doubling up on the interconnects (and halving inductance) would cause any kind of system incompatibility or oscillations. To an engineer a perfect wire is just a connection between two points and should have zero resistance, capacitance, and induction. The components act as there is nothing in between. If there is some impedance incompatibility it is the components incompatibility, not the wire between them.
In the real world wires have small amounts of resistance, capacitance, and induction and this can become a problem with longer runs. But I can’t see how a wire with LESS inductance causing a problem. Think of it like this. You have a 10 foot interconnect and it is safe and stable. If you switch to a 1 foot interconnect you will have 1/10th of the inductance. I never heard of anyone blowing up a system by using too short of an interconnect!
