Hope someone can give me some sound advice...
I currently listen to AT M50s powered by an ALO "The National" AMP from a Macbook Air via the headphone jack using Fiio cables.
I have some money that i want to spend on upgrading the system... but I'm stuck in the middle...
Should I purchuse new headphones (He-400s) or rather spend the money on a DAC (Thinking Schiitt Bifrost)?
The files i listen to are mostly standard iTunes purchases and Apple Lossless that I ripped from CD's.
