mundorf m-resist supreme vs jantzen mox and others

I really can't say as I have used these mostly on high pass boards. 

hi all,
i'm comparing mundorf mresist supreme vs mills mra12.
i find mills more dynamic and complete but on dry side then the mundorf.
why?
most or you say that mills are warm in comparison against mundorf.
i'm confused

More Burn in time needed. Different room, speakers, gear, ears etc... all play a role. 

so, mills mra need more burn-in time ?
does resistor has burn-in time ?

Yes, they both will change over time. Resistors certainly change over initial burn in time of say 60 hours...
