Does a new cd transport require break-in time?

Bad news:  As I was attempting to make an A-B comparison between the two machines, the Oppo crapped out; wouldn’t power up, leaving one of my best sounding CDs locked inside.  

Did you try unplugging it from the wall outlet for a few minutes then plug it back in? The Oppo may have just locked up. Universal players do that some times.

I tried several times plugging and unplugging the Oppo to no avail.

Now here’s a real queer problem:

After removing and re-plugging the coax cable between the DAC and the transport: NO SOUND!
Tried pulling and returning power cords and removing and replugging cable:
still NO SOUND!
Only when I added an optical cable in tandem with the coax did I get any sound.
Sound on both cables. The sound quality is fine.
This happened on two occasions.
Anybody have any idea what’s going on???

All in all a very aggravating day!!!!

After removing and re-plugging the coax cable between the DAC and the transport: NO SOUND!

On the Oppo?

No, on the Cambridge transport.

Just a guess you have the TOSLINK digital input selected on the DAC instead of the coaxial digital input.

Check which digital input the DAC is set to.
