Hello everybody, I can easily say, when it comes to Hi-Fi audio, that I am a big noob. I wanted to move my first steps into this world and I wanted to ask for some advice. I currently own a pair of Audio Technica ATH-M50x and I listen to music with a MacBook Pro via Spotify (with the highest quality settings possible: 32 kbit/s MP3). So I was wondering: how can I improve my experience? I believe my headphones are quite nice and everywhere on the web I see only positive reviews, or are they? Should I buy a DAC/AMP to listen to music or it would not make any difference at all? Should I start listening to uncompressed files?
Note: I am on a budget! I am sure that if I bought an expensive DAC/AMP I would hear the difference, but I wanted to know wether it is worth to buy a ~100$ DAC/AMP, such as the Shiit Fulla or the Fiio E10 Olympus, or what is the minimum amount of money I should pay in order to get a worthy machine.
Thanks to everybody who will answer me!
