This is pretty exciting. A portable with dual Wolfson dacs and versatile voltage supply. While hooked up to the USB the amp section will be running at a little under 5 volts but when on the 9 volt battery you will be running at the 9 volts.

Run time is around 9 hours for a 300mA battery and I would guess around 15 hours for an alkaline or a 500mA LiPoly.

Release date: 10 15 09


-Dual Wolfson WM8740 DAC Chip + TI PCM2706

--USB signal input, provides I2S interface for decoding

---Works as a DAC+AMP Combo, a standalone AMP, or a standalone DAC (Line out function)

----2-Setting Gain Switch for impedance matching

------OP AMP rollable

-------AMP section can be powered by either USB or 9V battery

Price: $219.00 plus shipping.

Wait wait... you can plug this in without batteries and it will work... holy ****.

They are totally different animals. The D4 Mamba is a USB dac/amp, not a player.

Does the DAC upsample???

new product from ibasso?

Grr. This means they're probably going to drop the D2+ in price.

I mean, it's almost perfect. Swappable opamps, USB/9V, what looks to be the same case as the D2, line out, and for almost the same price as a D2.

I wonder if there's a way to combine the voltage from the USB line and the battery. I know there's a switch at the back... but hmm... 14V...

Hopign for ibasso to release D11 instead...

That will probably be another thread. :^) No idea when though.

This thing have a charging circuit in it, or do you have to keep popping batteries in and out?

 

[achow]

argh, i hate this forum. shoulda heeded the motto.

looking forward to a review about this when it comes out.

it's almost too perfect. was going to get an ibasso T4 but now i might consider this.

Does anyone here have it on pre-order? and does that said person have RE0? very interested in knowing how that synergy will play out

Edit: for got to include the following two phones: AKG K271MKII and Senn HD650

I would bet that it doesn't have a recharging circuit because of the knurled fittings on the back. I like using the low discharge 9 volts though because they provide a better sound and then there is the 500mA liPoly or alkaline or lithium for the longer run.

Nice, too bad no optical input.

 

[charlie0904]

optical would be D11... their top end model.

I was actually thinking that it would be, for my Rockboxed iHP-120.

Hm, looking forward to more info on the D11. D4 also looks very nice though!
