Best CDP break-in procedure

Aha folks. Bought a "new tube" CDP. Wondering what is important to break it in most efficiently. Should I just plug it in and leave it on for a week or so w/o spinning a disk or feeding speakers? Should I put it the system? Since I'm told it will need about a week for the tubes, etc. to settle in, how can I run it full time w/o making alot of noise? Was thinking if it needs a load of some kind, would plugging in the headphones to that jack suffice? Best trick I know is learning from others' mistakes whenever possible. Thanks in advance for the wisdom. - Tom.
