AES/EBU vs RCA s/pdif into dac, RCA analog out


Hi, this seems like it may be a dumb question, but here goes. If you feed the digital signal into the dac via AES/EBU and then use the dac's analog RCA outputs to your preamp (preamp only has RCA input), would this result in a better sound than using the dac's RCA s/pdif digital inputs? Or would the results be exactly the same? I hope I'm making this clear: AES/EBU vs RCA s/pdif coax input in while  using analog RCA out.  I don't currently have an AES/EBU digital cable, or I would just try this out.  I am considering purchasing one just to see if there's any difference. Thanks for any advice.

I'm currently running AES/EBU and RCA Digital into my DAC and RCA analog to my amp.  The DAC has a remote control and all inputs are available so it's just a matter of switching inputs from the remote.

I'm not running any special digital cables.  That being said I hear no differences when I switch between RCA Digital and AES/EBU.  I want believe that AES/EBU is better but if someone switched the inputs I wouldn't be able to tell you which input was selected.  That being said all the equipment is in the same rack.  I suspect in cable runs over 20ft the AES/EBU would win.

The best method is try it and see if you can hear a difference. AES cables can be pretty cheap and tere are a lot of people who claim they can hear the difference. .  For reference I'm using the PI2AES / Raspberry PI for a streamer and to me all the inputs sound good.

Thanks Danager. Yes, I also want to think that AES/EBU digital input must be better, but that may just be prejudicial thinking. I will have to try an AES/EBU cable to see. To make a fair comparison tho, the AES/EBU cable should be the same manufacturer/model as the RCA s/pdif digital cable. Of course this means that if you have an expensive RCA coax s/pdif digital cable, you'd have to buy it's even more expensive AES/EBU stablemate from the same manufacturer. As an audiofool, I'm up for that. Just don't tell my wife!

There is no general answer, as in theory, the two inputs (coax SPDIF and AES3) should sound the same. In older or less well engineered DACs, one could sometimes hear a small difference between the inputs, but I have not noticed differences with recent DACs I've tried.

Try to get the cable on a money-back basis, is my advice.

(P.S. AES3 is the current designation for what is sometimes called AES-EBU.)
