XLR cable with warmth without losing resolution

Kimber Select 1116 which uses Kimber's best copper and is very natural sounding with good (but not overwhelming) harmonics and work well with tubes.  The other cable is a Purist Audio Design Aqueous Luminist.  This is an extremely well shielded cable that is dynamic and very well balanced top to bottom.  I am not sure what your budget is but if you can stretch yourself to the Aqueous Luminist it will be worth your while.

They say in Purist cables different lines have different sound. Unlike other cables where you get more of the same as you go up the line.

which line of purist would have the warmest tonal signature? (Keeping cost considerations aside)

What does one thing have to do with the other? 😳 Besides resolution and warmth are just words and words have different meanings to different people. Dylan said that. Everything is relative to something else. I said that.

In my system I sue WW Series 7 XLRs , power cords, and speaker cables. Whether the music is poorly mastered or wonderfully so, either comes through clearly

Use what recording studios use...Belden, Canare,  Mogami.  An astute studio owner has enough to deal with without having to buy 1K per meter balanced cable.
