Default Re: Audiophoolery?

One telling thing about all this audio 'esoterica', what with all the fancy/expensive mains leads and interconnects you can buy for audio, plus quantum stickers, boxes of coal ... and yet, for the instruments used in the serious scientific testing of such audio equipment, seemingly standard cable-sets are used on say, oscilloscopes, generators, analysers et al.

El boggo I.E.C mains leads, 'scope probes and signal leads of correct impedance, that's about it.

At work we play with cryogenics, measuring electronics down to pA (yep, Pico Amps) and MeV, and aside from job specific cable sets terminated accordingly, the power & signal leads are essentially, 'standard' (non-directional etc).

I'm told ice cream made from a dewar of LN2 is very creamy. LED's change colour in LN2 and PP3's 'go' flat, both recovering when back at room temperature. It was a quiet afternoon in the lab.
