For a while, I was using my ATH-M50 headphones for primary usage of listening to music. I never really feel too much bass when I feel it should be there, as well as plain missing details (not a basshead), and after doing some research, I discovered that getting a new DAC would help change that by increasing the quality of the music, and fully bypassing the need of a sound card. I have a few questions concerned about getting a DAC:
1. Do I need a DAC for my headphones to get the full experience?
2. Would I need to purchase an amp, or is a DAC all I need since the ATH-M50 has no real need for an amp?
3. Which DAC should I get assuming it is recommended for me to get one (my budget range is no more than $100 with amp added)?
I am also planning to get the Sennheiser HD 598 in the future not far from now. DAC and amp hybrids are fine with me. Thank you.
