500+ Head-Fier
There are a few "Class A" portable headphone amps to be found on Aliexpress. But whether they are any good is unknown unfortunately. Saw one sometime back that lists it suitable for 8~600 Ohms. Not sure if I'm able to find it anymore though.
But most of these are pretty battery hungry, as such a huge 4000mAh battery may not last 8 hours. Versus a tiny Fiio that maybe half or 1/3 capacity and good for double that !
