I just recently purchased myself an iPad Mini and would like to use it as my main music listening device. The headphone out provides pretty good audio to my headphones, but I'm pretty sure the sound quality could be slightly improved with an external DAC. I would prefer that the DAC would work right out of the lightning connection, but don't really mind if Apple Camera Connection Kit is required to make the DAC work. However, I do not want to hassle with powered USB hubs or anything like that. Does anyone here use DAC with iPad like this? Is this even possible? Which DACs are compatible with an iPad Mini? Thank you very much in advance for any input and assistance!
