Does a new cd transport require break-in time?


I just ordered a new Cambridge CXC transport to go along with  Gungy DAC.
Does it require any break-in time?

Very strange that the Gungnir doesn’t sound better with the Cambridge CXC once I hooed up mine to my McIntosh dac the improvement was immediate and substantial with explosive dynamics and huge soundstage maybe it’s due my Tellurium Black coax cable which allows the CXC to perform very well ?
At over $500 for the cable, I think I’ll pass, and try to find another solution.
