Preliminary message: I know the basics of both items from google searches, however I am looking for more in depth info like why one would use either.
I have a pair of Sennheiser HD 598's and was wondering if a DAC would help improve quality. From what I know Headphone amps just increase volume, so that would not be what I am looking for. Is there such thing as a portable DAC and if not, what DAC would be good for me (price range: $0-$170). I will be ready to answer any follow-up questions you guys have. Thanks for reading
