mundorf m-resist supreme vs jantzen mox and others

Sorry been tied up.....Fidelity is actually the perfect word and what high fidelity audio is all about. Here is the definition: "the degree of exactness with which something is copied or reproduced" So a component higher in fidelity is truer to the source, musical event, actual sound of the instrument or voice etc....

They sound more real and deliver more high fidelity. Horns sound more as they should etc... Hope this helps. 

Thnak you and sorry my insidiousness.
i understand what you but i would know more precise description if you can.
that's tmbre of high, mid, bass....imaging...ecc...ecc... and also which one between the two is darker than the other
i hope you answer 
thank you in advance

I really cannot speak to the bass. But the Mundorf is not as warm or dark as you say. The Mundorf has some added energy in the upper mids and highs in my estimation compared to the more neutral Mills MRA. The Mills is warmer compared to Mundorf in direct comparison.   That has been my experience. You can do a search and see what others think. 

Both image fine. 

There you go! This question is very system dependent as well as subjective preferences. I will help you directionally however by saying the Mills are warmer and the Munforfs are more turned up in the brilliance area. You know your own preferences and system personality so plan accordingly.
