Personally its the open spacious nature together with the amazingly fast detailed crystalline nature of the highs, throw in the excellent tight bass, in some cases like a reverberating ( not in a bad way ) wall of solid deeply extended lows( the tonality of the bass specifically ).Some vocals can be further out as well as some mids at times. Not right up front but also not completely missing.
In a minor way it reminds me of the Ultrasone S-logic with its spatial presentation, well the bass also. ( I hesitate to make that comparison hence the bold text)
It all combines together and just does something for me. Almost ethereal at times.
I don't know how else to put it for now, some tracks don't do as well on them and that might be due to their mastering together with some of the tuning on these.
I contacted someone who fully knows the ins and outs of original recording methods and they will hopefully pop in here soon to speak to this, but for now they are otherwise occupied with personal matters.
Sorry if i stated the obvious in the post here, sort of talking out loud to myself and separating what i find interesting and appealing with these. Probably didn't do a good job of the sound description.
Good points in the prior post on the separation and also the tip insertion. In my opinion shallow insertion isn't better, as has been stated in here before.
Gonna quit editing this and let it stand for now.
