Guys, sorry I was not at home so I couldn't provide link for the X3/C4 discussion but thanks to friendly members, it is already posted in here. As I said, why shouldn't I be serious? I just write what I read, I didn't listen to any of these daps. I was actually close to order C4 long time ago (that thing looks awesome IMO) but after reading comments about it I decided not to buy. In head gear section I saw many people who reviews the dap and disappears from head-fi. I found it kind of misleading for readers. I think you got what I mean.
Anyway, I really prefer to stop the discussion here, since the link is already provided too. The thread is for DX50 so let's keep it like that.
As a SE5way owner, after reading Gavin's comment about how good they pair, I simply get extremely interested in the dap again. However I still prefer to see it's final state (bug free and functioning correctly) to make a decision.
Also, I would like to read Sorensiim's thoughts about how it compares to its big brother DX100.
