How does it compare to a lyr2/asgard2/little dot mk iv se?   edit: will be using hd650 as well

So is your setup NFB15 -> Project ember -> HD650? Does the non-built ember require advanced soldering skills, or can a noob do it? Never done any soldering before

How does the AGD NFB11 pair with the HD-650 vs the AGD NFB15? I like warmer music signature, but also enjoy extra detail and soundstage. Priority would probably go to warmth/soundstage over absolute neutrality/revealing detail, as the setup would mostly be for just fun listening and not sound...
