1. 22g heavier (possibly the AAAs)
2. No integrated recharge (drat, drat, triple drat!)
3. Roughly 50% more voltage for the amp to work with
4. Line-out function for feeding into a full size amp

Did I miss anything? Oh, and it's not green.

It looks like it has been made less convenient as a portable amp in exchange for increased utility as a USB DAC. Agree?

Yeah for the size and the way mine is holding up so well the Viper is a real neat amp. I know they wanted it to be very stable and it is. Too bad it was a limited edition. With the HV opamp it is totally different. What a deal!

 

[RAQemUP]

D2 Boa's size is 51mm * 21mm * 82mm
D2 Viper's size is 51mm * 20mm * 94mm
D3 Python's size is 55mm * 21mm * 92mm

For the curious like me.

Edit: Is the D3 Python gray/silver? Can't really tell too well with the lighting and angles on the site.
Edit #2: Nevermind. Site says its comes with a black and a silver enclosure. That's pretty neat actually.

ibasso d3 is a nice upgrade with the line out but no rechargeable circuit is ********!

if i plug a d2 in my full size amp with the headphone out, what will be the sound? crappy?

interesting
what's your fav combination now ?

and also the faster - more aggressive combination for you

thanks

Sweet size comparison: iBasso D2 Viper vs Ibasso D3 Python vs Ibasso D2 Boa vs Cowon D2
....

 

[slwiser]

Are there any difference between the first editions and the very latest for the Boa. Thinking that it is not unusual for companies to incorporate some upgrades into a line over time.

Not sure because I was never looking for faster and aggressive, been looking for full bodied and details and mesmerizing. thanks

Can you drive stereo speakers with this? I was thinking of using it as external DAC for my PC to drive a pair of Audioengine A2s, and using it with an iPod when on the go.

Yes you can certainly use it to drive some speakers so long as you have the right cabling.

The speakers would need to be very efficient and reasonably small. You have to remember that the boa is limited in its power output in order to make it a viable portable option.
The new d3 will have more power than the d2. I am sure that is the main reason they have switched from the single rechargeable battery to 5AAs.

 

[sochee]

Well, the A2s are self powered (AC plug), plus they are bookshelf speakers and reasonably small, I guess...

 

[Tapiozona]

Sorry for the newbish question but I'm a bit confused when it comes to DAC/AMP combos like the Boa. Can they both be used at the same time or will I also have to buy a seperate DAC or seperate amp anyways?

 

[jamato8]

The Boa, RSA Predator and Pico, among others, have dacs that work with the USB output of your computer and can be used as a USB dac to the internal amp or you can use the Boa, etc, as just an amp but you can't use the USB dac by itself. So you have either a USB dac to the amp or just the amp using a different source for your headphones.

 

[asher7323]

Wow I read through 50 pages of this and it convinced me I needed a D2 Boa. I was pretty convinced by the 3rd page I think =/. I'm a pushover.

Sorry for my 187 dollars.

Probably the last thing I'll be buying until 2009 (Please, God?

) So excited to try this DAC on my crappy, crappy, crappy sounding laptop. Also I'm curious to see how it compares to my mint tins on the iPod.
