AES/EBU vs XLR cables for digital connection


I did look to see if this issue was addressed in earlier discussions but couldn't find any specific information, so here's the story: I've ordered a Sonnet Hermes streamer to complement my Sonnet Morpheus DAC, and since the DAC doesn't have the I2S port (it's USB instead, though I understand I can change this if I want to), the best available connection will be via AES/EBU. I already have a pretty good XLR cable (Clarus Aqua) which I previously used for analog connection but I'm wondering if there's any advantage to using a true 110-ohm AES/EBU cable or if the standard XLR (the impedance of which I don't actually know) will work just as well. Have any of you done an A/B comparison between these two types of cable? Opinions are welcome. Thanks.

I’m not familiar with the Hermes as I don’t own one but in quickly scanning the specs there is mention of using “Volumino” as an alternative to allow the use of Qobuz. Maybe this will allow you to stream Qobuz via the Hermes w/o having to deal with Roon? I don’t use Roon but I’ve read posts from others stating that it does have its own issues sonic signature.

BTW- Your 110 Ohm cable will be better than using a typical balanced cable and shouldn’t take light years to show the result.

See thread attachment for comments on Volumino- maybe you’re better off where you are-

I know you’re using Roon but I’m wondering if you’ve compared streaming without the use of your laptop. Have you compared Qobuz through your streamer when using the app via an IPad or phone without the laptop/Ethernet connection? If you try that and here an improvement (or not) it may help narrow down your focus.

I’m sorry to hear that you’re still experiencing problems with your setup- trying to help you get to the bottom of it all-

1) You confirmed that you could get Qobuz to run wireless- did you take the laptop (and Roon) out of the mix when running it wirelessly? Was there any improvement?

2) When using Roon with your laptop are you using Roon’s volume control, headroom leveling or EQ at all?

3) In case I missed this how are you passing audio from your laptop to the dac- usb  or Ethernet?
