Certainly we don't want to elevate form over substance. Objectivist want proof. That almost always means measurements.
An interesting one for measurement related proof is the digital RCA-cable connection between a CD transport and a DAC.
Why?
Because many digital S/PDIF transmission RCA connectors (termination and also electronic gear)/cables do not maintain 75ohm impedance correctly impacting upon reflection/eye measurement/clock-data/etc.
Yet it is interesting how some audio forum (various forums) objectivists view digital S/PDIF via RCA as a non-issue and that all cables-connectors-receiver chips are equal and so all digital cables sound the same; in reality the only ideal digital connection-termination is using BNC and probably I2S, with the complication of also requiring a well designed and implemented audio product.
Edit:
I think Hegel did some work to resolve this issues within their DACs, specifically relating to impedance mismatch-reflections.
