Now, that's a nice little DAP with quite the output power.
And gets extra points for cuteness and no-nonsense features. Me want a couple.

I wouldn't be too concerned about what's inside atm, although many people like these specs. Its about the sound and implementation that matters most. Take a look at the Shozy Alien thread, no specs have been released, all we know is many of the chips inside have been sanded to hide their identification, yet people love the sound, people sell their FiiO X5 and Sony ZX1 for Alien. Many company don't want to give these specs out as it's their secret recipe.

Main thing is that XDuoo made this player measure decently, particularly low output impedance and hopefully a flat frequency response when loaded so we don't suffer low end roll-off or any bizarre frequency alteration when using low impedance balanced armatures. I know one thing, it looks like a very cool unit indeed.

I just want to know if it is not a "aluminium enclosure" sansa clip !
Maybe it's more than this ?
