The problem is I don't want a power supply since portability is very much useful on a laptop and I don't have a ton of plugs in my room
Hey duke86fan,
I'm not sure which Dragonfly you're looking at, but FWIW, I recently got a Dragonfly Red as part of a promo with my Focal Elegia headphones and use them primarily at work. I tried the Dragonfly Red plugged into my MacBook Pro (MBP) via an Audioquest adaptor into USB C. Also tried going directly from USB B from a USB hub. The differences in sound quality between the built-in headphone jack (of the MBP) & the Dragonfly was barely noticeable. I was ready to return the headphones since I didn't think they sounded good enough to warrant the cost (compared to my Bose QC 35 II...the Elegias + Dragonfly were barely better but I was expecting to be blown away for what they cost).
I then decided to try the headphones on my home setup (tried from my Bluesound Node 2i and my Parasound HINT 6)...holy #$%, sounded a million times better than the Bose and I couldn't stop smiling! So I decided to keep the headphones and upgrade my amp/DAC at work.
Based on Z_Reviews, I tried an xDuo TA-10 hybrid amp with DAC (but switched out the stock tube to a Genelex Gold Lion). I thought it sounded better than the Dragonfly but not like my setup at home. I then ended up with a Monoprice THX AAA 887 and feed it with the Dragonfly Red. Much more analytical sound than my home setup, but I'm fairly content for now...though I am looking for a better DAC, haha.
So, I guess
my conclusion; be sure to test your headphones with the headphone jack of your laptop first and buy the Dragonfly from somewhere with a good return policy. In my opinion, the $200 MSRP of the Dragonfly Red, you're paying for portability and it'd probably be better served to look at a slightly larger amp/DAC from iFi, Topping, or xDuo.
BTW, I tested everything with Amazon Music HD, Spotify Premium & Mixcloud.
Good luck with your search!
