Jumpers for McIntosh MC225s operating in mono

.

This question is about McIntosh MC225s operating in mono.

Has anyone experimented with different types of “jumpers” (copper, silver, stranded, solidcore, etc.) to enable mono operation? And have those experiments produced results which are more musical than others? The McIntosh manual says “wire” and a friend who knows this amp has told me, half in jest, that a paperclip would do. The people I have talked to say that these jumpers must be solid and bare wire all the way.

All of the other cabling in the system (ICs & SCs), except PCs, is silver-based.

Experience and evaluations based upon experience, rather than speculation or conjecture, are of much more interest to me.

:) listening,
