I don't use the 850s with the X5 as they don't pair well together to my ears. The AK120 S-mod brings me what you mention of distinction of each note, with powerful dynamics and spaciousness. But depending on if I want to take that to the extreme I'd then use the 1Plus2 or SE5 :). The 850s for me are more so for enjoyment and not focusing too much on the details. Not that they are not there though. I find the 850s to excel particularly in gaming.
