Sorry Peter for the long time lost with me.

I have started a new forum about my project.

http://www.diyaudio.com/forums/digital-source/166290-192khz-24bit-dac-no-oversampling-no-digital-filter.html

bye

In any case I have ordered a pair of PCM1704 to start some tests.

Probably I will use a CS8416 followed by a AD1896 to resampler all the I2S input to 192KHz 24bit and after a direct connection to the PCM1704 (inv port for left ch).

I have lot of experence with AD1896:

Passive I/V with a pair of 50ohm MK132 Caddock and vaccum tube stage D3a SE with CCS.

Yes, I would like to create a project to play high resolution materials like the 24bit Studio 192 format (www.linnrecords.co.uk and www.2l.no).

Offcourse this should play also low res. material like cd ripped.

I am thinking to use a 192KHz 24bit usb to spdif interface like these and get I2S signals:

Peter,
Are this design able to play at 192KHz 24bit ?

There is No bit shift, no digital filter and No oversampling

The PCM63 are changed with PCM1704

Do you seel the dac pcb board ?

Any simplified schematic is available ?

Peter,
the schematic is private or public ?

Have you used a design like this one?
