Is it true that a digital cable has to acclimate to your system?

Just bought a Kimber Orchid AES/EBU cable and it doesn't sound good.  The seller advised me that a certain synergy won't happen until the cable gets used to the other components in your system.  
 
I am using a Bel Canto CD-2 for a transport and a Bryston BDA-2 for a dac.  The Audioquest Cinammon AES/EBU cable I have sounds much better.

thanks for any wisdom on this.
Ted.
