Things to consider
1) quality of interconnects
2) is the player leveled properly
3) clean AC?
If you have paid attention to the set up and ancillaries then perhaps there is something wrong with your player. I have been through over a half dozen disc spinners and this is easily the Most musical of all. I replaced a CD player that cost $1599 with the Marantz. No going back!
Please report back. I hope we can figure out what is amis.
