Do Interconnects need to "warm up"?

All I can speak to is my own experience with silver cables. The difference was not always night and day, but it definately decreased my enjoyment of listening to my system (s) over time.

I suspect AF is correct.

My technical gut instincts (which usually serve me pretty well) and personal experimentation with ICs tell me that what matters is the physical configuration of the IC, its impedance characteristics within teh system it exists in, its ability to transmit all frequencies in phase and ability to shield/protect against external EM fields when needed that mostly matters.

USe of exotic materials just ups the cost and snob appeal perhaps but probably is not a major factor in sound.

Just my technical gut assessment. VEry little relating to ICs is proven in the usual scientific sense.

I think Hifihvn makes sence of cooling cables vs. worming up. Designing freeze packs for cables might be the next crazy tweak in the audiophile business.

Maybe - all things characteristics change with changes in temperature, especially metals. It would be interesting to measure electrical characteristics of interconnects before and after use.

Chrisr,
Make sure your measuring device handles magnitudes of 10 or more decimal positions.
