I don't have much experience with modern hi-fi DAPs/Amps, but they don't need an amp when used with the one I do have (HiFiMan 901 with IEM card). I imagine other decent DAPs are similarly capable of driving them. Why not the HF5? It's in that price range. The VSonic VC1000 would be an alternative. Maybe even a T-Peos H-100 if a v-shaped sound is okay.
