I'm looking for a desktop (can be portable as well) amp / dac combo for < $300 (ideally) that sounds better than the audio straight out of my MacBook Pro. I just auditioned a NuForce Dia, which I had bought to power some desktop speakers and also used it for a headphone amp. Honestly, I could not tell the difference between the output of my MacBook when powering headphones. Previously I had an iBasso D2+ which did sound a bit better, but only a bit. So I'm wondering is there anything in this price range that will give me a nice improvement in SQ over my MacBook?
BTW - The head/ear phones I currently use - AKG K550s, AT A900s, and UE Triple Fis.
