If I recall you also have the M1. Thoughts on the M1 vs. the N3?
I am looking forward to a shootout of the Shanling M1, M2, M2s, and the Cayin N3. Somehow I am guessing the Cayin will have a similar sound signature to the M2s. So it may come down to preferred user interface. The Cayin does play native ISO files, which is a cool feature for me.
I am currently in Red - Black with the LZ-A4. I find these are like a version of the Lz-A2 but on steroids. Similar low end; much better high end. For the money they rock; but I still think the FLC8S is a step up; but that step up comes at a price.
I would choose N3 over M2s, no matter how M2s looks nice. The 4.8 ohm output impedance of M2s is a deal breaker for me. Especially when you try low impedance iems like FLC8s.
