Hi, a newbie here, I wonder if anyone can suggest some $200-$300 DAP, preferably ~250? I need something that supports instrumental genre like rock/ballad with enough bass (tl;dr common daily use with no EDM) and goes well with my M50x cans (the legendary entrance headphones )
For the ATH-M50X headphones, I would not spend more then $100, maybe a little more, for use with the M50X. Maybe get the FiiO X1 DAP ($100).
If you believe you're truly happy with your 50s, stick with them. General consensus would say there are definitely better headphones available.
