To me it means less shrillness.
Sometimes the “S” sound, like when you say snake, is very shrill sounding on bright speakers.
If I turn the volume down enough, at some point the shrill S sound is all you hear. The rest of the lyrics and instruments are not really audiable but the cymbals and S sound in lyrics can still be heard clearly.
With a “warm” setup, the S sound isn’t so shrill and when the volume is turned down, the cymbals and S sound in lyrics is no more audiable than the rest of the frequency range.
