XLR cable with warmth without losing resolution

Use Zetor II Avia...
they are under grand/m and just awesome...very warm, extend the soundstage a lot...

Cardas Clear sky or higher will fit what you are after! Very musical cables all around. 

IMO, the Purist Poseidon has the exact traits you are describing at at your price point.  I will tell you that the cables are heavy and unless you're working at floor level, they will need to be supported with some sort of cable ties. 

Purist Neptune seems to keep coming up in my research. But I can’t try before buying where I live. Will the Poseidon give me enough taste of the house sound?

@essrand, 

If appearance (I know some people are into that) and brand pedigree matters most to you then by all means go for Purist Neptune or Poseidon. Either of these will give the Purist ‘house’ sound. Purist cables are pretty good and they have a strong following. I have owned full loom of Musaeus and Venustas in the past. Check with thecableco,com, they may have a loaner for you. 

You no longer have to spend thousands of dollars to get great sounding cables. If transparency, richness and realism is what you going for then you outta to try Audio Envy cables. They do come with 45 days in-home trial and you will save $$$$.

Good luck!
