I have done a good amount of research in this area recently for a friend. I would recommend a Schiit Gungnir (I bought one, for my office) … although, honestly I would stretch and get the Yggdrasil (my friend bought one)… an outstanding deal that performs far beyond its price level. These are incredible for the money, natural, detailed with great dynamic range.
None of these devices are going to have a headphone output…. Well because they do not contain an amplifier.
I don’t want to tell you what you should want, but a remote for a stand alone DAC… would be putting money into something almost no one would use. You only have one source. Playing with the settings is something seldom done by most folks.
Just as reference, my other systems are show by clicking on my ID… so, I am used to auditioning DACs of much higher quality.
