Very Interested.

Would this be available as a kit with all the SMD devices mounted?
I would like to do a bit of DIY to save some money.

I am interested in this DAC also. But I cannot see where to register for Grouo Buy 2. Where can I register for Group Buy 2?

audiodesign (Andrea) just created the list. You're first on the list.
A GB list is progressive; every new participant should ADD to the list.

Hi Quang Hao and Andrea,
I'm impatient for more information about the discrete output stage!
Earlier you indicated that the power supply is still being developed, but is the main circuit tested and working?
Are you happy with the sound?
What's the current draw?

Quanghao have tested the new shunt without op-amp on a single power supply of the first DAC module and the sound is good, no differences and less problems to keep it stable.

We have tested the new output stage with a prototype on one channel and the result is much better than op-amp.

In any case I think that Quanghao will produce a first little series of few pcb, 2 or 3 items, to test if all is ok.
