High Res Files and Maximum Length of Digital AES/EBU Cable

Here's my observation:

I connected a Mutec MC3+ smart clock device via its AES/EBU digital output with my DAC (emmLabs) using a Mogami Gold Series digital AES/EBU cable (110 Ohm). The length of the cable was 10m (ca. 33 feet). While this worked for 16/44 files, it did not work for higher resolution files (24/88) and higher. "not work" means either silence or a lot of noise and crackling.

 

I guess that's due to the fact that the cable was just too long. But on the other hand in professional studio environments they also use rather long digita XLR cables.

So I am a bit puzzled...

I believe the maximum length is 1,180 feet.

 

Something else must be going on.

Here’s what my source says. 
 

AES/EBU cables are designed to maintain a characteristic 110-ohm impedance and sample rate should not be an issue provided the cable is built according to this specification. I’m guessing there might be a hardware issue with one of his or her components if it is not passing anything over 44.1, that or the cable in use is somehow compromised but I think that is unlikely.
