New speaker cables recommendations sought

There is no such thing as a "warm", "musical" wire. As for "atmospheric", I do not even understand what it means....listening under the rain perhaps ?

Let me correct myself. You can indeed get warm wires if you pump excessive current through a wire not rated for it :-)

You guys really should really read the following:

Do not skip sections, read it in its entirety, I will give you an exam on it sometime in the future and I expect everyone to get a passing mark :-)

Teh_chuksta. I am trying to save you some money that is all. Unless you are operating in the megahertz frequencies or running wires longer than 100s of feet, any standard typical multi strand copper wire rated for the correct current, costing no more than a few bucks will do. 
Just do not tightly coil them, keep them straight and away from signal wires. 
The rest is just illusion and delusion.

None of it matters in audio frequencies. About 80% of what is written here is pure delusion.  
Again, read the article well.  It will enlighten the delusioned.
