Ayre Codex DAC

Anyone know the maximum length to run USB to an Ayre Codex DAC. In thinking about purchasing one that is 3 meters. Is that acceptable or to long?

5 meters is considered the limit for a USB cable without an active repeater. 3 meters is fine.


I use a five meter Pangea cable with my Codex and it works perfectly.  
The previous answer are spot on. But, why not contact Ayre directly for the best information? They answer emails faster than a call.
