Combo Streamer/Headphone Amp

I would not recommend a Node just for headphone listening.  The headphone section of the Node N130 is an afterthought.  The headphone section on the Node X is supposed to be much better, but you'd be paying $750 for a unit where headphone listening isn't its primary function.  However, if you're looking for a stand-alone streamer/DAC for your main system anyway, then the Node X might work for you.  But I would not get it just for headphone listening.

As @soix points out, using your phone or tablet as a streamer along with a dongle DAC (like the Dragonfly series) or a headphone DAC/amp might be a better alternative.  Cheaper, better sound, and much more portable.  I'd investigate something like the iFi Gryphon or the iFi Hip-Dac 3.

@soix @dinosore Tanks for your input.  I hadn't considered a dongle. I have a late model Samsung tablet that would work for this. Do the dongles provide a charger passthrough, or am I either on charge or on dongle? 

Well, I’m an Apple user and they offer an adapter that allows you to charge and stream simultaneously, so there’s probably something similar for your Samsung.  Here’s the Apple version just fyi…

But, I found this adapter to sound much better than Apple’s if they have one that’ll work with your tablet (shoot them an email as they’re pretty responsive), but it won’t charge as you listen…

Hope this helps. 

Consider a miniDSD SHD Studio. (Qobuz, Tidal, Spotify, Pandora, Roon+) You’ll have to research the HP amp power. It has plenty for my planars.

@panzrwagn If you're worried about draining the power of your tablet, you can also look at DAC/amp combos such as the ifi HipDac or Gryphon.  They have their own internal battery. They are not quite as portable as a dongle DAC, but still pretty small.
