Looks promising, mainly interested in if the battery is user replaceable. Mentions dual battery, but if it comes with two to swap out I'm all in.

 

[raps1514]

Excited for it. Those specs + compact form factor (as every DAP should strive to have) would be the dream.

"Waiting for the details. A user-replaceable battery is a smart move."

 

[Ben86]

There is no info about "user replaceable battery" for dx340. I don't think that this option will be available for this dap, otherwise it would definetely be anounced in poster as an advantage.

 

[Skev]

I think they mean two different batteries for different purposes like the DX320?

One for the main unit and a separate for the amp section?

Correct, but there is no info that these batteries will be user replaceable. Very interested about the new Ibasso developed DAC

Correct, but there is no info that these batteries will be user replaceable. There will be no more user replaceable amp cards. Very interested about the new Ibasso developed DAC

It still has swappable AMP cards.

I worry that stainless steel will add too much weight. DX320 was 310g and borderline pocketable, this one might be just too heavy to be pocketable.

I'd also guess that battery won't be as easily accessible as with DX260 due to replaceable AMP cards.

Is that a spelling mistake from their website?

Is that a spelling mistake from their website?

No. It clearly says interchangeable headphone amplifier card.

 

[Silverlinings]

I think ibasso just posted on Facebook that it will have “easily replaceable battery”.

Yes I saw it just now. I hope it is r2r and class A.

 

[nioh]

It should be the same DAC that’s in the D16.

Not really, on DX240 with replaceable amps, it's pretty easy to change the battery, Ibasso just didn't advertise this feature.
