DX100 vs RWAK100
OK. I've spent many hours listening to both my DX100 and my RWAK100, using my UE PRM CIEMs. The biggest difference between the two player's SQ, for me, is sound stage: the DX100 simply sounds wider. Both players sound very good, but the wide sound stage on the DX100 is just mind blowing, and the RWAK100 isn't quite as good in this regard. A more subtle difference is bass response: I find the DX100‘s bass is a tiny bit more articulated than the RWAK100.
So, in my very humble and inexperienced opinion, for my own personal taste, I feel the DX100 has a bit of an edge over the RWAK100 in sound quality.
The UI and UX on the RWAK100 is EXTREMELY superior to the DX100 in every possible way. The UI is much faster, much more responsive, much more intuitive. Music never randomly skips. Music always plays immediately when I press play; it doesn't randomly skip the first 0-3 seconds if I start playing from nothing like the DX100 often does. I can adjust volume and change tracks without turning the screen on. It never makes my IEMs pop. I could go on and on, but a lot of this is already known. Put simply, the DX100's UI is something not even a mother could love, and it infuriates me, and the AK100 UI is beautiful and pleasant to use. It's not quite iOS level, but it's a hell of a lot closer than the DX100.
The vastly superior UI of the AK100, and intolerably bad UI of the DX100, is the reason why I am considering something that others have said defeats the purpose of having a AK100: using it with an external amp. I love the UI but I want it to sound like my DX100.
My question: which portable amp, with a optical input, can I use with my RWAK100 to make it sound like my DX100? Does such a thing exist? Is an iBasso D12 with a particular set of opamps what I need?
What does everyone think? Thanks!
