First full day of listening at work (computer job, sys admin). Didn't listen to it ALL day, but maybe almost 4 hours out of a 8.5 hour day. Used up around 50% of the battery.
I was definitely a little skeptical about what the DX200 would sound like compared to what I've been using for years... Note2 to RSA Predator DAC/amp. But gotta say... this thing sounds awesome! No disappointment at all with the sound quality. Using single-ended out through Silver Dragon 2 to Westone W80. Even for a semi-bass head like myself, who really likes a warm sound signature, this has plenty of that, and so much more. The high end and instrument separation is killer... but still very smooth without being harsh at all. And, like some others said, if you're listening to tracks that have bass and sub in the mix, you will hear it.
I can kinda understand how it's sometimes being described as analytical sounding rather than fun. But for me... it's definitely a fun, detailed sound signature with the W80.
I'm only using the Mango OS player, as that's all I really wanted this for... a portable killer "reference" DAP... and it is. And I plan to burn it in the old fashioned way, as it sounds great out of the box to me. There's only a few little niggles with the player, like a little slow on the swipe. And it could definitely use some sorting options based on tags. But it's nothing that gets in the way of enjoying that great sound! Really looking forward to the firmware updated to allow using 3rd part Android music apps at native resolution. But I'm more than happy with the Mango OS player now.
Firmware version I seem to have is 1.6.2... and it's not listed as a download on the iBasso site. So I'm a little hesitant to upgrade it right now, as the player is working great as it is.
So, I thought the sound signature "low end" and "impact" might be an issue compared to what I was using. But it's not at all. VERY happy with this as a portable DAP. I would just about say that the DAC and associated analog circuitry alone is worth the price of the DX200 (and I'm using a Benchmark DAC2 DX at home). That you get a portable DAP, and late version of Android on top of it really makes this an outstanding value. So far, I lover it!
And looking forward to seeing how much it gets tweaked to be even better as new firmware updates are released.
