The original Chord Hugo would be great as it has a great headphone section and decodes almost every format. Can be used as a preamp as well. For a little more, the Border Patrol DAC and the MHDT Orchid seem to be checking alot of boxes for alot of music lovers. Small form factors both although if hi rez is your thing, these 2 are not the solution. After listening to either, I’m not sure you would be missing anything anyway... Full disclosure, I have a new iPad with the usb/power adapter feeding via USB cable to a Border Patrol DAC at my office fed by Roon/Qobuz/Tidal streaming. It is terrific and no complaints. My home dac is a 5 figure retail piece and I have absolutely no complaints although the recommendations above are NOT at the same level as my home dac. All depends on what you are after.
