warmest speaker cables you've heard?

All speaker wires must come in the following temperature configurations:
Warm
Medium-Warm
Medium-Cold
Cold.

Maybe Tide should come out with a line of cables. 🤔

But honestly folks, if your system is a tad bright and you need warm sounding cables to ameliorate that, that will not take you back to neutrality. It's just a sideways move to make it more pleasant sounding, which is what the OP was asking for. 

All the best,

The big heat cable.

Raven Audio makes some decent cables. They're a tube amp company (Nighthawk is stellar, and would give the likes of Hegel 95 a run for their money), and their cables kind of carry this sound signature. This is just my ear's review.  

First cables are most definitely tone controls or there wouldn’t be so many successful cable companies on the market, and many 20+ years in business. There’s definitely a difference between cables unless one simply has a system that is not revealing, they have poor hearing or maybe just a bit hardheaded. 

Kimber makes nice cables but 8TC is far from a warm cable. As others have mentioned stay away from silver or silver plated copper conductors. Cardas and WyWires are both copper litz cables and tend to have an open, natural presentation that many call warm. Silver cables tend to be very revealing and some are great and some can sound a little cold. I think plated, at least my experience can sound a little harsh or fatiguing. 
If you drop Alex of WyWires an email of your system and what you’re looking for, he can build you a cable more on the warmer side… assuming you believe they’re tone controls.

@adg101 thanks for the info and suggestions! Very useful. I have some wywires items (had the headphone cable, and have power cords on order) but have not tried their interconnects or speaker cables.

This is turning out to be a nice discussion on speaker cables. Thanks, everyone, for all the input provided. I appreciate hearing from both sides.

I placed an order for a short length of deulund speaker cables from partsconnexion and am awaiting delivery. I figure they were "cheap" enough to just give them a go. I am still going to get another one or two sets of speaker cables to try out. And I have a friend who is going to lend me his tellurium Q black ii.

U guys are great!
