I am currently building SSMH (Starving Student Millett Hybrid) amplifier and need a portable source that will be a good match for it. This will be for a bedroom headphone system but space is limited that's why I can't go with a desktop source like CD player or a turntable. HTPC is also out of the question.
So are there any budget friendly DAPs that have decent DAC and can output line out to the SSMH? Please do not recommend iPhone or anything that is expensive. If I had that kind of money, I wouldn't be building Starving Student amp. :)
