iBasso D42 "Mamba" with dual dacs! !! Hey Hey! Improved Starting on Page 76 . - Page 7

post #91 of 1153
Hmmm, another thing just came to me as I was browsing the forums. I might be wrong though.

This D4's specs look quite similar to the iBasso OEM project. Both use dual wm8740 right? I wonder how would both compare? At least on the dac section

Hi jamato8,

I am just thinking to buy a P3+ because I don't need a DAC in my portable rig. Have you compared the D4's amp section with P3+'s? I want a portable amp can drive my HD650s to a kind of acceptable level. If the D4's amp section is better or equal to p3+, I definitely will go for D4.

Regarding D11

I've sent an email to iBasso about the release of D11. Got a response advising that they have no intention of releasing something like a D11, but in the next 6 months there would be an improved version of the D10.

I have just begun to listen to the D4 so it will take time to hear what it is capable of but at this time I will say the amp section is of a high caliber and sits up there among the best portables. HiFlight may have compared the two more.

Thanks jamato8, I am looking forward to your more comparisons.

So... a D10+ then? I wonder what they would change.

The P3+ has more options as far as opamp selection is concerned. It can be buffer, 3-channel or 4-channel architecture.

Both have a 9v capability, however the P3+ can run from an external adapter, whereas the D4 cannot.

I find the SQ to be very close between the 2, I am sure that from strictly an audio standpoint, either would suffice.

The final choice is whether or not you mind changing batteries fairly often in the D4 (9-20+ hours, depending on choice of opamps) or whether you value the ability to roll opamps in the ground channel of the P3+.

Another consideration is that the P3+ uses only single-channel opamps in the buffer sockets, which limits the choices somewhat, whereas the D4 uses the more common dual-channel opamps.

I would probably suggest that if there was no need at all for USB capablility, the P3+ would likely be the first choice. If you anticipate the need for a superb DAC now or in the future, the D4 would probably fill the bill just fine.

Hey Ron, just a quick question. Which headphones/earphones do you sort of use for these portable tests?
Cheers...

So you need battery to make use of the 9V function?

Can you use the D4+ while charging simultaneously like the Pico? And if yes, at what voltage?

The D4 does not charge the battery. You either need to use an alkaline or rechargeable batteries and have a charger for them. If running the D4 from the USB you can run the dac and amp from the 5 volt input. If you want to use the USB and the 9 volt output, then you will be running from the USB 5 volt for the dacs and the 9 volt battery for the amp. But yes you can charge batteries and listen to it at the same time, though the batteries won't be inside the D4.

I use about 4 different phones for most of my testing:
Sony F1
Yuin G1A
Yuin OK2
Westone ES3X

For ultimate power output, the last trial is with my AKG K-340s.

This about covers the full range of phones, from circumaural to supra-aural thru IEM, from very sensitive to very demanding in their power requirements.

A particular opamp combination must pass muster with all the phones before I will recommend it for consideration, as some combos sound good with some types of phones, but not others.

Thanks HiFlight,

Now as the amp sections are the same level, and I am not a big fans of opamps rolling. for me the bettery life is the main consideration. Do you know normally how is the bettery life of P3+?

Second, I think the D4 will have higher re-sale value.

On rechargeables, I believe the P3+ runs about 20-25 hours. This is very dependent upon the number and types of opamps used. If both V & G ground sockets are used, playtime will likely be less. IIRC, the stock configuration ran about 25 hours before SQ suffered.

I believe that using a single LTC6241HV in the D4 with dummy buffers will outlast the stock configuration in the P3+.

With the stock configuration in each amp, the P3+ will outlast the D4 due to the higher milliamp capacity of AAA cells over 9v.

Of course one can use the P3+ with an external 9v adapter and have unlimited playtime.

Has this been confirmed by iBasso? Or are we talking about Ryuzoh's plans?

Same here. Which sucks because the wife was going to get me a D10 for Christmas. Now I am wondering if I should wait till the updated D10. I was really looking forward to the D10 too.
