It has one dac for each channel.

Will you be getting double the perceived audio gain from the PICO? That extra money can go to new cans, IEMs or a DAP and some nice cables and a six-pack of beer!

What's tempting me about the D4 is the low price considering it uses the same Dac chip as the Pico...
Chips are half the battle. Its how the chips are implemented. Even with 2, I would be suprised if the Mamba amounted to the Pico. One thing that people seem to forget is that the Pico DAC upsamples, I don't think the Mamba does that.

It is all conjecture until you have heard it.

The amp section of the D4 is excellent and the dual dacs do a great job of retrieving the data and presenting it as Music.

Hi jamato8,
Sorry, I haven't read the 6 pages, but, did you test this mamba ?
The D10, IMHO, is really weak on the USB entry.
Is the D4 better ?
Cheers,
Pat

Yes, the D4 DAC performance is better than that of the D10. There are a few other components that are upgraded as well.

The amp section also does justice to the improved DAC performance. It is a very nice sounding unit.

With 5v power selected, there is no battery power utilized when using the USB input. Using the Aux input with 9v selected, the battery life varies from about 8 hours to over 20, depending upon ones choice of opamps. (This is using 230mah rechargeable cells)

It should be possible to get over 30 hours using alkaline cells with the 9v/Ext Input option, again depending upon the selection of opamps.

I find the SQ of the D4 when using the USB input to be very similar to that of the D10 with the optical input.

Hi Ron,
Thank you for your answer, you're a gem!
Cheers

I very tempted to try one, too bad there are only a few ways to do this without actually purchasing one.

Well...

Not to hijack the thread, YES!

If it made no difference, ALO and others would not be in business and to boot this site would not have the same popularity

Really I wouldn't say that. There are plenty of businesses that provide useless services. That being said, if you are looking for a long term and reliable cable, it does not hurt to buy a 100 dollar cable, especially if your portable rig costs over 1 grand.

Also, remember when you are paying for a quality product, a lot of the time you are paying for excellent customer service. I don't have an ALO cable, but the big reason I bet ALO keeps such a strong following is because their customer service is really great. You can tell just by reading the ALO forum and feedback threads.

Huge sonic differences? I would say no to minimal, but there is more to a cable than its sonic capabilities. Bad quality cables break easy.

I really like ALO cables, But I get most of mine from monoprice.. And their CS and quality have been fantastic.

I have been using the amp section more than the USB as I use the optical out of my iRiver to an optical in dac and then the D4. The D4 amp section is excellent. I need to let the USB section of dacs run in for a while but it does sound very good but I can't give a detailed opinion yet.

Can't wait for an actual review of the D4, just waiting on that before I decide to get it or not. And excuse me for bringing the thread off topic there about the cable.

How does the dac on the D4 compare to that of the Pico so far?
post #88 of 1153
The D4 has no optical output right? Damn wheres that D11.

That would be an optical input, no it is USB only.

Running one low-draw LR opamp with bypassed buffers, I have just passed 24 hrs run time still with no distortion. This opamp functions down to 2.8 volts, so it is squeezing every bit of juice out of the 230mah rechargeable.

I think the greatest appeal of the D4 will be to those who listen to a lot of streaming music or otherwise use USB a lot. With the appropriate opamps, one can use the 5v position and still get great sound out of the amp without using any battery power at all. Also, using the D4 DAC pass-though to another rig uses no battery at all.

If you want a first-class USB soundcard that you can still carry with you, the D4 is a very logical choice.

I believe the D4 is an example of iBasso thinking outside of the box.

Using the D4 just as a basic amp is added frosting.
