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?
