One of you have sent me a email asking for some questions regarding the DAC.
Why not post it here and let Andrea answer you instead ?
There is no Group Buy that I know of for components other than the AD1865, which is unfortunately already fully subscribed.

Patrick

Hi!
Start when i test good about all PCb!
My acount: quanghao168@yahoo.com.vn
Thank!
i think next weed we will start make pCB! I wating Andrea test good about the new I/V stage *no use tranformer*
Thank very much!

Whether you need 2x AD1865 for balanced output and what the circuit would then look like ....
I thought this is best answered by someone who has actually developed the original circuit.
Happy New Year and thanks for sharing with us, Andrea,
Patrick

Yes, it is possibile get a balanced output using 2 x AD1865 but I don't think this will give a best sonic performances.
A balanced output mean the necessity to add a differential output stage so it will increase the complexity and the cost.
A balanced stage can eliminate some distortion and power supply noise but here we have, in any case, a very low distortion stages and a good power supply.

Here the final output stage
THD measurement with and without 10Kohm load.
Output impedance less than 1Kohm
Power supply voltage about 270V
Ik = 2 x 8mA
Freq = 10Hz at -0.7db
Vout = 2Vrms with an input of 154mVrms
THD = 0.3% thd max on 10Kohm load

Here others attach
To prevent dc voltage on output durung switch-on and switch off phase a relay will short the output to the ground for some seconds.
The delay circuit is the same used in the my design of Monrio Top-Loader CD Player (value 10000$).

Someone else was happy with a direct transformer (Sowter 9545) output on the AD1865.
That way you can get balanced output for nothing extra.

I have Sowters in my CDP done by Modwright, back when I was more afraid of digital mods. I dont have the schematic, but the unit sounds wonderful. The IRON anyway, cannot be that bad. It does not use any tubes.
hi quanghao, befor order the full set PCB i'd like to know something about the DAC.
i hope you would forgive my bad english and mine deep ignorance.
then: which type of transformer i need to complete the power supply and the rest of the DAC?
where i can find the AD1865?
ebay?
there are a lot of fake on ebay(opamp, capacitors, etc etc)!
thanks and sorry everybody for my stupid question.
