I plan on getting a headphone DAC/Amp and have pretty much decided on the Fiio E10. Small, looks lovely, and gets god reviews. However, I'm looking at the E09, and wondering if it's got a DAC in socket, why does the website say you need the E07 to use it as a DAC/Amp combination. Can I not just use the E09 alone? Is it JUST an amp?
Apologies if I'm missing something really basic.
