I use silver plated copper (6cm) between the WaveIo and dam 1021. No problems.
Going to use silver (about 7 cm) for the connection to the 2 mono 1121. I am working on that setup.g

Me too.

Related to the disabling of FIFO and considering this, ( Would it be possible to connect 4 or 8 boards for each channel to enhance dynamic range ) - something like totaldac d-1-12 ?

Dear Soren, any news on this very important feature of disabling FIFO / PLL so we can use high end low phase noise OXCO ?

It would be great to be able to do this on my dac1541 also ( s/n 011 )

I understand that source jitter would come through but i plan to use very low jitter source. Please make this available.

Just curious... how do you plan to synchronise your new clock and the data you feed the DAC?

htpc usb out -> sync to usb/i2s converter -> oxco ->multiple dam ? I think...so i will use the same frequency clock on the entire chain ?

Basically i'm looking for advice and suggestions. What interests me in a 2x2 so 4 dac1121 in balanced mode all synced from the same clock with i2s lvds in.

And second thing that interests me , and moreso than the first would be to be able to sync 3 separate dacs from the same clock. so 3x 2x2 or at least 3x dac1121.

I suggest you look into Ian's FIFO and DualXO boards. Those have one i2s input (for interfacing with say usb-2-i2s module like Amanero) and multiple clock outputs as well as multiple i2s outputs reclocked by the same clock in the DualXO board.

I have Ian's McFIFO/McDualXO installed (w/ Amanero and just one DAM1021) and it does work although without the onboard-clock-bypass firmware update the DAM1021 is still being driven by the onboard programmable clock hence not reaping the full benefits of the upstream clock.

Hope Soren could implement this feature soon.

Last night i have put power on a dual mono 1121 setup for first testing.
It has a WaveiO usb to I2S converter and dual mono 1121 boards in master mode and xlr outputs.
It worked at once
I did not use a programming board. But used all cables on the headers for the inputs, outputs and config pins.

Can't say much about the sound yet. Sounds offcourse similar to the dam 1021 V2 i have (single board setup).
Testing was with bad cables and there has to be burn in time.

Thanks for the suggestion, it's definetely useful !

I'm waiting on this feature and am curious how it can be implemented with ian's mcfifo in such a way as to run 8 soekris boards in balanced configuration.
