Listening to my M8 via my iphone 5S on LCD 2.2s balanced. Listening to the Phish 2013/07/17 Alpharetta, GA in HD ALAC (pm me if you want a link to this outstanding show/recording). I was A/Bing from my Audio GD Ref 10.32 and the M8. The M8 is pretty impressive and holds its own impressively. Worth the wait and its time to sell my pico power-I just cant see using it anymore now that I have compatibility with idevices and this DAC.
