Also, one can play with the configuration of the ground channel with different opamp combinations in the P3+.

For those who like to experiment with various architecture configurations and opamp choices, the P3+ is a good choice for a basic amp.

While the D4 lacks the ability to use an external power adapter and has a fixed ground architecture, the dual DACs and excellent amplifier quality make it a good all-around choice.

FWIW, if I was forced to keep only one of my iBasso amps, it would be the D4.
but for home wouldnt the d10 be much wiser descionespecially for playing xbox via its optical toslink input, plus its coaxial, dammit i wish more portavles had these options more interconnect the better and toslink is far better than usb imo

I spent about 2 hours to listen it until now. For my esw9s, I didn't notice too much different with unamped directly from ipod. ( a little disappointed, ).
But when I use it to drive my HD650s and K701s, I was so satisfied with it. Just turn the knob at 12:00, the volum are pretty aloud. The bass is deep and tight, middles are smooth and highs have a lots of details, clear and bright. Compare with my home rig(see my signatures), it sounds more cold and bright but with a thin body, and highs are a little hiss. But for a portable amp to drive the 650s and 701s, what more can I expect?

For the the DAC part, I would like to say, it is amazing. I use foobar2k WASAPI to USB input of my LIttle dot DAC1 and D4 to little dot MKIII. I found the two DACs at the same level. Little Dot has a better bass and the D4 with a little more details at highs.

Plus my little dot DAC has more than 200hours on it and the D4 only has less than two hours.

Will try to write more impression after it burn-in.

i am looking forward to this review

how does the little dot dac compare to the d10
and does anyone know if there are any other small portable amps like the ^ that have both usb, optical toslink,,,,and or the additional coaxial
toslink is a must

At 5v it plays about as loud as a Predator or D10 which is moderately loud but not really loud like the 3MOVE or V1, and the HD600 lack punch in the bass with 5v at high volumes (similar to Predator and D10 when pushed too loud with HD600). But at 9v the D4 really kicks it into gear and the HD600 seem 3-5 dB louder with better bass impact. I'll have more power comparisons in my upcoming review, but for now the D4 at 9v is useable with HD600 for bass-heads, and only slightly behind the 3MOVE and V1 in power.

Also, the peeps asking about Livewires with D4, it's a great match. Same with ESW10JPN.
good to know,

obviously the d10 and predator run on 5v while connected to usb, but what about when both are used with wall adapters and in the d10 optical toslink and wall adapter, and what is the rechargable internal battery of the d10 run at ?
----i also have found that the predator while using its usb could not full amp the low end of my denon 7000.

The D10 and Predator both run at 5v no matter what, and they both charge with 5v power.

I don't think it would be fair to compare a modded D10 (Topkit and BG caps) with an unmodded D4.

^ you would be suprised how good the new D4 "Mamba" sounds in stock form. I was really surprised by it, would send it to you to try but it is already out "on tour" with three other members. Meanwhile I am waiting for a "topkit" from HiFlight. Cheers.

Interesting, how does it compare to your SR71/SR71A on the amp section?

I believe Jam's D10 has BGs and a Topkit as well. And he also has a D4.

I would have bought one if it had a coax &/or optical SPDIF. I'll wait for the next one from iBasso.

Looking forward to adding this to my collection after significant burn-in and now play time with my D2+ Boa.

This would be the DAC to get if I get a laptop in the near future I'm pretty sure I won't need a (dual) DAC coming from my Walkman/iPod touch 3rd gen to P-51 Mustang would I?

You are correct, in your application, the D4 DAC would be unused.

The dual DACs in the D4 are only used with a USB input, such as from your computer. Inputs from a DAP would be to the Aux Input/Output jack of the D4.

I guess it boils down to whether you feel the P-51 or the D4 would exhibit the best synergy with your iPod Touch.

I never cared for the sound out of the SR71A, IMO the SR71 is much better (musical, detailed, and extended). Sadly I sold the SR71 to pursue buying an AKG K1000 so I can not compared the amp section of the D4 "Mamba" to the SR71.

Hi all -- I tried asking this in another thread, but didn't quite get conclusive info.

I'm using the D4 on a Vista box -- I find that I have to quit/restart audio apps when I plug and/or unplug it into the USB. Other folks seemed to say that they didn't have to do that -- but then iBasso told me that is the expected behavior.

So just looking for a reality check from a few of you -- do you find that you have to quit/restart audio apps when you plug/unplug the D4 from USB?

And thanks...
post #299 of 1153
I only have to play next song on the list or stop then replay the current one when pluging the D10 (It should be the same with other USB dacs) not the whole application.

This is the same for me on:
Foobar on windows
mpc/mpd on linux
itunes on OSX Leopard

Thanks, that's interesting info -- so, with those combos of app & OS, once you step to the next song, it resets to the new audio out, without having to quit/restart the app?

Just curious, what happens if you're playing Web/Flash audio? For example, browsing YouTube or some such?
