These are power hungry. Probably. You can get pleasing sound off a good smartphone or a DAP. That would not be my first option. Or second option; the more power the better. I've used these with a Galaxy smartphone, a FiiOs M11 -portable DAP, which according to Z-Reviews (on youtube) has more power than the M11 pro. I have plugged them into my Denon receiver which is fed by an OPPO disc player. Also, have them in a counter-top set-up and it is just not the same as listening to them as having this plugged into the THX AAA 789.
Without knowing your listening habits or desired endstate, its hard to say. If you like low volume delicate sound, maybe. Probably not. There are some really good options out there, over the ear and earbuds. I really like my Ether CX's and they do sound great on my DAP, but my DAP does not get the same result as my home set-up.
So to answer the question, in my opinion, yes. They need a clean source and amplification.
