warmest speaker cables you've heard?

I've had the Kimber and wouldn't call it warm.  I played around with various wire doing the DIY thing briefly and came across Polar Wire Products (www.polarwire.com).  I was told a pricey power cord used their copper wire in a doubled up configuration so I gave it a try both as power cords and speaker wire.  It's quite warm alright with pretty good detail and lots of body.  And it's cheap! cheap! cheap!  Just for the hell of it, why not buy $20 worth of the single run cable and see if it meets your needs?  It may not be aimed at audiophiles but its pretty good.  

I believe the new (as yet unseen) Loki will support balanced cables.  Better to wait for that then flush your money away on tricks.  To be honest, any cable that has any kind of audible effect with the miniscule length you're considering MUST be defective, purposely or otherwise.
 

Acoustic Zen or harmonic technology, OCC single crystal is the best wire for audio.

If your system sounds somehow harsh, maybe you should start addressing the core of that problem.

If you have a good music source (analog or digital) and decent cables, I wouldn't spend money on new cables. I would try different inexpensive tweaks that will help "cleaning" and improving resolution, leading to a more real and warmer sound. I mean antivibration pods, ferrite cores, tube damping, etc.

Also consider AC treatment, a big source of noise and harshness. Of course, AC power filters or AC regeneration is not cheap, but maybe a dedicated AC line is cheaper. All of them will help a lot. 

Actually, my system is far from harsh..
I built up my system around the Susvara and I think it is just about right.

I have demoed the Raal in my system twice now, and have decided to go ahead and purchase it (traded with a dude from Canada who is taking my ZMF Verite in exchange).

So I'm aware of the sound of the Raal and, with all else "equal and optimized" (or so I think..), the only other component which I do not have yet are the speaker cables. And since I have to purchase a set of speaker cables no matter what, I'm taking this opportunity to try and get a set with the "warmest" sound possible. 

On a side note, I've really no issue with folks saying that cables can't sound warm or be used as tone controls etc. Everyone is entitled to their opinions. I figure, no harm trying. If anything, expectation bias and placebo do definitely exist as well, but as long as it manages to increase enjoyment of the hobby, I don't see why not too.
