warmest speaker cables you've heard?


I'm looking for a short length of speaker cables, which i need to be as warm as possible..
Price wise, looking at USD700 and below for 1m length pair.

it'll be placed in between an Apollon stereo 1et400a power amp and a RAAL-requisite SR1a speaker adaptor box.
The SR1a is ruthless and clinical and I am looking to add as much warmth as I can. 

Assume the rest of the gear and interconnects have been decided/cannot be swapped out. So just left with the speaker cables to sort out.

I've been told the following are good candidates:
Kimber 8TC
Tellurium Q Black II
Tellurium Ultra Blue

Anything else I should be looking at?

Cardas Golden Cross! These are the warmest cables I have heard. I used them for twenty years until I was able to improve my electronics. You can buy used for half price. 
If you want to warm things up a bit, try some good quality stranded copper or go even one step further and try some tin coated, stranded copper. You can even throw in a mix of silver plated copper to get that sound.

All the best,

thanks! quite a few recommendations for Cardas. I will look into the Golden Cross but it is a legacy item and i dont think my local dealers have it; may need to source it from overseas and/or second hand mrktplaces

@oldhvymec that is interesting info! thank you for sharing. yep, its the Raal SR1a ribbon headphones.

@mglik thanks! i've not come across them before but will go and look through their website.
@nonoise 

thanks for the suggestions! the only company i (think that I) know that uses tin coated copper is Final Touch Audio (i may be wrong..). could you point me in any other direction for this metal combo?
Supra cables are the ones I used to use that have the tin coated copper wiring. Warm sounding with a relaxed top end and a nice, rounded bottom end. Not the last word in detail but they'd do the trick. 

Madisound is one site that carries them stateside: https://www.madisoundspeakerstore.com/supra-cables/

And for overseas, there's :https://www.av-connection.com/?ML=350

and their own site: http://www.jenving.com/products/sword-3
off to the left is a "catagories" section to view the other lines as well, besides the Sword, which can be expensive.

And for about the same price, over on eBay you can bid on some Zu Audio speaker cables and get a great deal with a low, winning bid.

Good luck and all the best,
