So here is the big question with the release being near. What are you going to mainly attach the M8 to? I think for most people is the ipod. I definitely pluging it in my Galaxy Note2, Ipad3, and using it as a portable amp/dac for my mac book pro. I am thinking about getting a nice combo going maybe with the ak100 or ak120 or even the dx100 (which I love but also lost on an international flight).
I seem to be the only one who's going to be using the M8 exclusively with my MacBook Pro and LCD-3's. (Although I have 2 iPhones and an iPad, I don't use them for music listening.) The M8 will be a replacement for my old and trusty DACport, which still sounds great, but I'm fully expecting the M8 to surpass it in every respect. I've got several 24/192 files that I'm anxious to finally hear in full resolution.
