I'm not sure that you aware about this, but many AK120 owners have sold their players once they auditioned the ZX-1. Like the AK240, the ZX-1 has a wifi streaming ability via the custom DLNA application as well. I was able to stream hi-rez contents from my portable wifi drive very easily. The ZX-1 is top notch in term of sound surpassing my MS-AK100 very nicely. The ZX-1's UI is just way superb.
That would just make the case of increasing competition even stronger...Okay let's wait and see what new DAPs 2014 will offer.
The AK120 doesn't do it for me - just didn't wow me (sorry folks) had my hopes on the AK240. Anyone has more info vs. the AK120 can't wait to hear it.
