pardon me if i should have posted this in the amp section. I got the grado 225i recently and have been listening to mp3/flac straight out of the headphone jack of my '09 macbook pro.
it sounds great to me but i seriously can't hear any difference when playing 128/192kbs mp3 and flac of the same song, which leads me to think that maybe i am not realizing the true potential of the headphone.
will getting an external amp+dac combo improve the sound quality to a stage where i can differentiate the 2 formats? i have been searching the forums and there are people that swear by an amp+dac for the 225i, and some don't. rather confused.
for my current setup, what would be the next thing i can do to improve the sound quality?
