What does 'cold' mean? What does 'warm' mean?


Aside from the 8 year old 'hey go open a window' replies; explain a 'cold' sounding cable? A 'warm' sounding amp?

Yes. That one.

Indeed, the terms don't precisely adhere to scientific criteria, but it all becomes obvious when you find your ears sweatin' or shiverin'.
