How does the RSA Shadow pair with the SE846? Looking for an AMP to use with LO from iPod or other Hi-Res DAP. I'd be using with an Lightning to 30-Pin adapter and newest nano or iPad mini. I have a RSA Tomahawk already, but RSA reccomended the Shadow to pair with the SE846. Still screwing around with high res source units. I really don't want to go the phone route, although I do have a new HTC One M8 on the way, maybe I could pair that with an external DAC / AMP. I started with the Fiio X3, but quickly became frustrated that it cannot read ALAC track tags properly or sort them properly. I then ordered an iBasso DX50, but this one hisses like mad on any of the 3 gain settings with the SE846. Not sure if that is the sound signature of the DX50 or what. I am hoping the Fiio X5 may be the answer to my problems for high res audio files. I'm tempted to try the HM901 with the IEM card and be done with it. Everyone says it is one of the best if not the best.
