I recently bought a pair (effectively brand new) of RHA MA750i's off a friend and I had some inquires about getting the best sound quality. I know they require quite a long run-in time, if anyone knows roughly how long I would appreciate to have any rough time. I have also read about the impact of adding a DAC to your sound set up and wondered if it was necessary for the headphones I have. If it would be good to get one any recommendations are appreciated, although if it were portable and compatible with an iPhone, as well as as good value (as far below £100 as possible!) it would be perfect. Any advice would be much appreciated as I'm quite new to the whole headphone scene.
Cheers
