Hello Quanghao or Andrea,

A couple of questions:

* Will you be offering a LL1684 output stage option?
This post from Quanghao on 11/8 seems to hint at the possibility. I also noticed that build has a firewall-type divider between the r-core transformer and DAC to reduce EMI/RF interference. Did you find the extra shielding to be beneficial?

* Do you think a PIC programmer will be needed with this version?

Thanks,
Sten

 

[doctormord]

10x330u, you serious? I (personally) don't like the pcb-layout for several thermal reasons. But well, you doing what you do.

If he does, then I'll change the output stage to LL1684
still waiting his confirmation though...

 

[quanghao]

Here is the layout for the dac, 3d display, when completed it will be the same!
I will race the earliest information about the production of DAC for you!
thank you for your interest!

 

[danielkol]

Hi, Quanghao and Andrea!
It seems that second version of Dac board is quiet different from the first one.
Have you resolved issues with Spdif and shunt oscillation?
Does the second version sound better?
Thanks, Daniil!

yes!

Hello Quanghao or Andrea,

HI!

[CaféNoir]

Could you try to reduce the trace length between the DAC chip and the decoupling caps? It should increase performance substancially

[anjogi]

Hi all,

i am a little confused now. I first asked wether to use an alternative outputstage my own Audionote stage. Then i thought it's better to use the proposed stage.

Now an alternate solution with the transformers is possible.
When i would prefer the transformer stage, what have i to do? Have i to correct recent list here and subscribe the other ?

thanks
jogi
