At 100hrs it should start showing you what’s what. At 200hrs usually it will more or less settle. 
What cables are you using and what is the rest of your system.

Critical listening starts at the 200 hours mark.  What other Gear and Cabling is in your system?

Merry Christmas

Are there filter options?

Many factors involved including your room which many try to "fix" with gear/cable changes. IMHO, cables can become expensive tone controls. CD players do have their own "flavor". Best sounding of the many I have owned was a Cary unit. Incredibly smooth and natural, beat my McIntosh unit IMHO...

Agree you should give it another 100 hours of playing time before making firm conclusions.  What CD player were you using before?  Are there improvements in other areas?  What interconnects are you using and what’s the rest of the equipment in your system?
