Eventually I've gone through all the pages of this thread, what a project!

So what's the difference, in terms of components and circuit design, between the P3+ and the amp of this project?

Can late comers join in and buy this OEM P3 once the final version is out?

 

[SpudHarris]

x2?

 

[DarKu]

The OEM Project has exactly twice the power of P3+
that alone tells a lot, there are also best components, gold platet PCB and Jacks, best materials and best op-amps used, all of it for the size of the iBasso D1, too bad we cannot order the OEM project

i would kill someone to have one

 

[SpudHarris]

This must be some amp..........My P3 with the right chip set is astonishing and I would put money on the SQ being better than a few amps costing considerably more so god know what this must sound like.

Can someone answer the above and put our minds at rest one way or another? Will latecomers like myself be able to purchase this or not. If so I'm in, if not I'm going to cry in my beer this evening!

The basis of this amp is.... "higher voltage can bring higher performance".

Difference between P3+ is voltage, size and chargeable.
And, its feature is selectable circuits to find one's best configuration.
To join and buy this amp for latecomer, all I can say... please become patient until 3rdQ.
iBasso already began ordering for parts of this.
In 1st batch, you can take it with AD712JN and 3 BUF634Ps on it.
But from 2nd, I'm planning to make 2 versions.
Clear version and Soundstage version.
Clearer one is based on mixed cap configuration what John is listening now.
Suitable with OPA211, OPA827, OPA2111, AD797, AD743, AD712, AD8610/20, LM4562(LME49720/10), LM6172, LT1028, LT1364, LT1113, NE5534...
The other one is based on blackgate version I'm testing now.
That will be sold w/o blackgates, but you can ask me to change if stock of them are obtainable.
Suitable with OPA627, OPA637, OPA602, OPA604, OPA211, OPA2107, OPA2111, AD843, AD743, LT1037...
Preference must be different by individual, so......just finding your favorite is the only way to solve, then I named this amp as Quest.

John, if you prefer to test the BG version ASAP, I can send it before the updating and repairing

When you say the 2nd batch will have two versions, do you mean the 2nd preorder, or the Q3 group?

I wish I saw this thread when it just started but I just know it recently. Any idea the price for the BG version?

 

[wuwhere]

Who makes BG caps nowadays?

 

[jamato8]

No one makes the Black Gate and it does not appear they will ever be produced again so all that is left is the NOS.

Nichicon has some nice caps at good prices but I need to listen to some to get some impressions. I am not sure there will be an equal to the nonpolar Black Gates though. I have a stock of them because they are that valuable to me.

Nops, 2nd is estimated to debut in the 3rd quarter of this year.

You know, the BlackGates are obsolete and in trafficing stock only.
Steady way is to buy them in stock from parts connexion by yourself, and send me what you bought.

In Japan, stock of them had been already run out.
Also, Rubicon in Japan was entrusted to manufacture BlackGate, but that didn't profit for them.
Thus they stopped production suddenly in 31/08/2007.
I think they will NEVER produce BlackGate again.
So, I recommend you to stock.

What version of BG caps should I try to find? Like the capacitance, the size, ...

Forgot to ask, what is the difference between the 1st and 2nd batches?

First, The price.
Second, the parts will be more higher graded like below OPAMPs and caps.

It is estimated to become around $320 in normal (AD712JN + x3 BUF634Ps),
caps are MUSE FW 10000uF/16V, MUSE KZ 47uF/25V, Elna Silmic2 47uF/25V.

Clear version (x2 634s in L/R channel, P & U) will be around $360 w/ AD797AN,
caps are MUSE FW 10000uF/16V, UTSJ's 100uF/16V, MUSE KZ 47uF/25V, Elna Silmic2 47uF/25V, MUSE ES 47uF/16V.

Soundstage version (x4 634s in L/R channel, 2x P & 2x U) will be around $430 w/ OPA627AP,
caps are UTSJ 10000uF/16V, UTSJ's 220uF/16V, MUSE KZ 47uF/25V, MUSE KW 47uF/16V.

This is just under planning, but I'll make effort to maintain this price.

 

[arirug]

I really look forward to this, and I will for certain buy the best one of them as soon it is ready for sale!
