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?
128x128docroasty
By what mechanism can a speaker cable boost or attenuate signals selectively within specific frequency bands?

I suppose that in a particular room, music might sound very subtly warmer or brighter when you introduce a slight change in gain solely due to a change in cable length or gauge. Even so, couldn't one manage those effects more effectively via DSP, tone controls, room treatments, speaker placement, etc.?

@tk21 the speaker cables are for a Raal speaker adaptor box. To SR1a headphones. These are extremely resolving headphones and from what I've read from other users, the headphones will reflect upstream cables and components.

If there is even the slightest chance some cables are going to give me a "warmer" sound, rather than accentuate/cause brightness or harshness, well it is a chance I'd be willing to take and spend on.
You want cables that are neutral. If you have overly bright speakers then maybe buy a warmer sounding speaker such as a British made speaker, wharfedale, tannoy, spendor, harbeth, etc..
