Take a look at the Chord Mojo. It's the current dac darling for mobile. Might be a bit more than you thought about paying but I can confirm that it gives my full size, Audio Synthesis DAX a run for it's money which was about 6x more expensive.
There is a soon to be available add on for Mojo called Poly which will allow playback via pretty much any wireless channel (blue tooth, wifi, DLNA, Chromecast, Roon, etc.) as well as give you an sd card reader and the usual usb / spdif inputs.
