Jax2 you a right in a way.
Well, since I was just stating my opinion it really isn't a matter of being right or wrong. It's just my opinion.
But i also asked for a cable not being warm. Isnt that an easy q to answer ?
No, it is not an easy question to answer without knowing what amp and speakers you are using. As Rsbeck implies, different cables will interact in different ways with different systems. These differences may be quite pronounced, for instance if you are using them in a tube based system vs. a SS system, or they could be quite subtle.
