Hey everyone, I ordered a set of M4U1 headphones, and have been wrestling with what DAP to go with as a good pair. I've been looking at x1-x5 fiio and dx50-90 ibasso so far. But to be honest, I am lost in the reviews of all of them. Maybe information overload at the moment. My initial plan was to go X3. Price is ok. Is the DX50 a better pairing for these headphones though? is jumping to a x5 or dx90 worth it with these headphones? Looking for your thoughts.
