Driving 2 DACs with 1 source

Why do you have the Alpha USB converter in the chain at all? Why not plug USB cables into each DAC? I've used computer server with multiple USB ports and run two USB cables from computer into each DAC. Et voilà!

the best solution for this is get a good quality ddc - for example a denafrips hermes or gaia or gustard u18 -- it will also cleanse and reclock your aes input and drive multiple dacs via its numerous digital outputs

@jjss49   Thank you!  This is the exact component that I was looking for.   It will solve the problem by providing 2 independent AEB outs and can also eventually replace the Alpha USB with its USB input. Great!

@oberoniaomnia Because neither DAC has a USB input.

@lanx0003   These cable solutions seem to be for analog.

Can a cable work with digital without causing timing and clocking issues ?  Will the 2 devices lock onto the signal without interfering with each other?

You are correct, Op.  Sorry I miss that.  The spec. also says 69 ohm nominal impedance, not 110 ohm for the digital applifcation.  And you have self-corrected for using splitter for connecting source to two DACs.  The noted risk could likely happen.

I should spend time and take a look at your equipments first.  Now I wonder why don’t you simply connect your alpha DAC to DDC via BNC port using a 75-ohm BNC cable, and connect your Camira DAC to alpha DDC via AES port using a 110 ohm XLR digital cable.  Two different outputs with a switch control in the back of your DDC and you are done.

Of course, if you are thinking about investing a better DDC than the expensive Berkeley alpha DDC will be another story.

Also I am puzzled about the reason you did not do so is because the SQ from BNC port is inferior to AES so you are thinking about AES splitter?  But then if you switch to different DDC that does offer two AES ports, you will run into the same issue.  

This would be easy to do with Roon and a Rasberry Pi end point. :)
