Denis,

Please write direct to me to resolve the problem. I shall need more details and not just a simple description of the problem.

Buzzing noise can be the digital filter is not set properly in the correct mode.

Hello Spencer!
Recently I have completed the assemblage of D1V3 DAC. It souns great!! Really a top performance!
Now I am thinking to use sometimes my notebook as player too, but it has only USB output connection obviously.
I am searching a USB to SPDIF converter or a good schematic in order to realize one DIY.
What do you suggest me about it?
Many thanks. Best regards.
Davide.

Frankly speaking, I never use USB connection from PC as I have many source. Thus I think you can try to get one simple and cheap on to try and thus you may want to upgrade the crystal in future. I think the only format available today is 16bit/48k and there is not much 24 bit USB receiver available from the market yet.

Thank you for your feedback and enjoy!

Hi guys,

Spencer has posted some mods for the D1V3 on his website. Has anyone tried these and can you report on the results here?
