Although not life-critical (such as aircraft), I have worked with (but alas don't own) very good RF electronic test instruments from the likes of HP, Tektronix, LeCroy, etc. Yes, they used gold plated connectors in some cases (oxidation causing non-linear junctions is a measurable effect). Yes they used cables of the right characteristic impedance for RF connections (transmission line theory is also 'proper' science and can be measured). But not one instrument ever used 'exotic' cables.

I'll start believing in this audio snake oil when it's used in 8 digit DMM's, 'DC to Daylight' spectrum analysers, and the like.
