I think it´s very important to consider that most people reviewing DAP´s don´t do any proper A/B testing. In my humble opinion thats because they do sound fairly similar, and nobody wants to admit it. Seeing that you already are interested in the lower price segment, i would recommend getting a DAP with some Headroom to drive high ohm cans. I´ve tried some Fiio Daps, and didn´t like the software in all cases, so thats something to consider as well. for example Fiio sorts by Genre and then you get all the songs of that genre in a List, no artist, no album nothing...
If you don´t mind the size, in my opinion LG´s V series phones are an excellent alternative (if a phone is an option for you at all) they all sound very good (you get a v10 for 60 bucks with an included headphone amp an ESS dac), and you get a lot of bang for your buck...just wanted to throw that in
