I seriously wonder how in heaven's name can an interconnect make a really discernible impact on the sonics

Assuming the cable is well shielded to prevent in/out EMI interference/leakage, and the connectors aren't loose

My rusty memories of electrical engineering tell me the difference in the IR of the 5-7 mm (?) length of a brass/silver/copper interconnect would be of the order of 1/10000 ohms, give or take a few basis point between brass/copper/silver

or perhaps it is my bronze ears
