My logic to get the LX version vs. the idevice version was:
A: I wanted optical in to enjoy my live music shows from my TV
B: At the time, I needed a new phone. I knew I would be getting an Android phone over an iphone, and thought the Galaxy s4 would work seamlessly with external dacs(not necessarily true). I figured I'd kill two birds with one stone, buy the 32gb version of the s4 + 64gb micro sd.
C: I did not want to convert my Flac files to apple lossless. Now I know there's a Flac player app, but that would mean I would have to buy an ipod touch, and max capacity is 64gb for those, so why buy a phone and an itouch when I could have it all with the s4.
In theory, this sounded like a great plan...
Unfortunately, at this point in time, the only way to use a device such as the Hifi-M8 with my S4 is through an app that isn't meant to be a player, but a recorder app. Compared to a proper music player app like poweramp, USB Audio Recorder Pro interface sux major balls!...but then again, it's not meant to be used in such a way, and lots of us are just thankful it even exists!
Anyhow, I'm starting to miss apple's no bs interface, and no buggy bs.
So in conclusion, for those of you that are considering which version of the M8 to pick, know that if you intend on using your M8 with your Android smartphone, it is NOT a perfect M8ting!
