Shanling CR60 how to open

Dear DIYers does anyone know how to open a Shanling CR60 CD transport?
I have a slightly modified Tempo ec1b CD player that sounds better fuller and cleaner.
I have tried to open the CR60 but did not succeed.
A different linear power supply makes a difference but not enough the Tempo
CD player when used as a transport still sounds better.
I hope to be able to upgrade the inner power supply and perhaps the clock.
Anyone tried with success?
Thanks
