Portable DAC/Headphone Amp Recommendations

@akg_ca The thing I do like about the Audioquest is that it’s so small that it doesn’t interfere with my activities. I’ve even done my Muay Thai kicks on the bag while listening to it. Out of all the options, I believe the Chord would be my first pick but it seems too large for my purposes.

You might find the Topping DX3 Pro+ is a good fit for your requirements. At 4.75 X 1.25 X 5.5" it's pretty compact, it uses a decent ESS ES9038Q2M DAC chip and supports coax and optical inputs up to 768/32 and USB up to DSD512; and Bluetooth 5.0 with LDAC and aptX HD. As a headphone amp, it delivers 1800mW into 32 Ohms, meaning it will drive just about any dynamic headphone with lots of headroom - including my notably inefficient HiFiMan Sundaras - with a very quiet, detailed, clear and neutral signature. Setup-wise, it offer 7 different rolloff filters, and +6 or +19dB HP amp gain, for starters. And it comes with a nice big display and a remote. That it does all this for under $200 is quite an accomplishment.

@panzrwagn Thanks for the input. The Topping would be a bit awkward for my needs. My primary goal is to find something that I can use at the gym. I know that may seem odd however, I spend a lot of time there and music is a motivator to make me get out of my chair. At this point, I’m wondering if I can justify both the cost and the size of the Chord Mojo 2. I’m thinking Velcro, rubber bands, etc…to make this endeavor a workable solution.

Sounds like the Dragonfly works well for your needs.  I’d just suck it up and listen without it until the exchange comes through, and a 50% discount doesn’t exactly suck.  Oh, and try not to drop this one so much.  FWIW.
