I have no personal contact with Sony devices anymore. The ZX2 costs $1K+, I believe. That's more than an AK100ll. I'd suggest starting out low, and seeing what you like.
The Mojo is expensive, but it is meant to pair with cell phones. No point in buying a good DAP if you're going to get a Mojo. Just plug it in to your phone.
Everyone has likes here. Read up on things in your price range before jumping in. Figure out what you need, and what you just would like. You could buy a Fiio X1 for a hundred bucks. That might be enough for you. Or maybe the X5 2nd. Or any number of other low or mid-range DAPs. Or go all in and get the Mojo.
That's what makes this hobby fun.
The ZX2 is also less than half the asking price of the AK240, significantly less if you import the Japanese version, like me. I just can't stand AKs horrible value proposition, at every tier there's alternatives that come close/are better while costing much less. The only one I haven't demoed was the 380, simply because I thought the asking price was ridiculous
But I agree with what you mean, that's why my first question was what his sources would be, we really need to understand the use case before making a meaningful suggestion. Hopefully he will chime in with some feedback. I've been curious about the new Pioneer and Onkyo DAPs as well, they seem an interesting possibility, hope to hear them in person as well soon.
But here's a question to you (I'm guessing you've been at this much longer than me, given I only started about a year ago), knowing what you know now, and probably wading through a lot of mid-tier DAPs, IEMs, etc first before levelling up, so to speak: If you had a chance, would you have just gone big for your initial purchase and saved up for a flagship?
I've been pondering this a lot recently, maybe I should stop trying lower-end stuff, save cash and just make 2-3 big purchases a year, and call it a day. I guess making resolutions can't be avoided at this time of year
Edited for clarity.
