I've heard these kinds of improvements before and I put it down to ever decreasing jitter.

For the small outlay, and ease of installation, it's a no-brainer.

Hi Fran,
another question:
What of the 1-4 Output Mode Selection have you used in your DAC?
Just to make an idea for its setting.
Many thanks again for your help.
Regards.

Davide.

Hi,
many thanks for your gently answer.
But I meant the 1-4 Output Mode Selection of the "WM8804 to CS8412 converter board". Because I have to solder the resistor, I have before to choose the setting, and I have not understood the exact meaning of that setting.
I am thinking to solder the resistors on a kind of jumper in order to can change the settings.
Can you gently suggest what may be the best solution?
Thanks a lot.
Davide.

Default 10KOhm potentiometer

Hi,
I have purchased a good quality quad 10KOhm potentiometer for my amplifier.
I ask gently if D1V3 (D1V33 upgraded) can drive this pot with the original 10uF C4 C15 C25 C36 ?
Can I keep my (expensive) 10uF C4 C15 C25 C36 caps, or can the frequency responce be compromised?
Many thanks. Regards.
Davide.

Default About WM8804 to CS8412 converter board again

Hi, excuse me for my misunderstanding.
Reading the .PFD guide, it seems (for me) that using the WM8804 to CS8412 converter board on D1V3 (D1V33 upgraded) it can works only at 16bit (mode 1 and 4 resistors combination).
If it is so, how can I choose between "Right-Justified Mode" and "I2S" selections?
I have not the Know-How to proceed the choise by myself.
Can you gently help me another time?
Many thanks. Best regards.
Davide.

I think the document has explained that clearly on page 1.

Hi Spencer,
I have already read it before!
But it is a description for all the possible combunation and usage. With a D1V3 DAC, can I use all the 4 output mode selection?
For D1V3 picture shows only 16 bit Right-Justified Mode. Is it the only selection mode that I can use?
If I had known this, I would not have posted the question, don't you think?
Many thanks. Regards.
Davide.

For SM5842, it can only do Right Justify mode (RJ) at 16 bit mode.
For PMD100, change all to Left Justify mode (LJ) for 16 to 24 bit mode.
On PMD100 converter board, cut trace pin 13 at bottom away from +Vcc and tie it to Ground at pin 14.

Hi,
Ok!
And about J28/J29 how have I set them?
With DIR9001 and SM5842 they had not effect to output mode. But now with WM8804 (RJ mode) and SM5842, have I to set J28/29 for 16 bit mode or not?
Thanks again.

Hi,
again:
on my D1V3 board, J21 and J22 can switch between Dir9001 mode and 8412 mode (it is written just so); now with WM8804 how have I to set J21&J22??
Thanks again.
Davide.
